3. NAMES AND FUNCTIONS OF PARTS

■ LEDs

• POWER

This LED lights when the S5U1C62N51E1 turns on.

•HLT/SLP

This LED lights when the CPU enters HALT or SLEEP status. (The S5U1C62N51E1 does not support SLEEP mode.)

• AD0

This LED indicates the status of the address 0 (AD0) signal. It can be used to check whether or not the S5U1C62N51E1 works.

• SHEXLD

This LED lights when segment option data from a personal computer is loaded using the in-circuit emulator ICE. As result, it can differentiate whether the currently specified segment option is due to the ROM (S.HEX) or has been loaded from a personal computer. Refer to the development tool manual for the S1C62N51, 6S3N7, 60N01, 60N02 or 60N05 in regard to the loading of the segment option using the ICE.

Note: Be sure to use S.HEX created by the segment option generator compatible with the S5U1C62N51E1. Data

created by the old segment option generator cannot be used.

• LFHX

This LED lights when function option data from a personal computer is loaded using the in-circuit emulator ICE. As result, it can differentiate whether the currently specified function option is due to the ROM (F.HEX) or has been loaded from a personal computer. Refer to the development tool manual for the S1C62N51, 6S3N7, 60N01, 60N02 or 60N05 in regard to the loading of the function option using the ICE.

Note: Be sure to use F.HEX created by the function option generator compatible with the S5U1C62N51E1. Data

created by the old function option generator cannot be used.

• CSDC, SWRUN

These LEDs indicate the values ("1" or "0") of the following registers. LED lights when "1" is set in the register, and it goes off when "0" is set in the register.

CSDC CSDC register (address 0FBH•D3) SWRUN SWRUN register (address 0F9H•D1) (Available only when S5U1C62N51E1 is set for the S1C6S3N7.)

• OSC1XT

This LED lights when the OSC1 oscillation circuit is set to crystal oscillation by function option.

• OSC1CR

This LED lights when the OSC1 oscillation circuit is set to CR oscillation by function option.

• HVLD, SVDON

These LEDs indicate the values ("1" or "0") of the following registers. LED lights when "1" is set in the register, and it goes off when "0" is set in the register.

HVLD HLMOD register (address 0FAH•D3) SVDON SVDON register (address 0FAH•D0)

In the actual IC, power saving needs to stop the HVLD and SVD functions when they are unnecessary.

■ Test pins

• RS, TH1, TH2, CS pins (sockets)

These pins (or the socket) are used to connect external parts, such as resistors, thermistors and capacitors, when using the R/F converter When using the connecting pins, pay attention to the stray capacitance of the connecting cable and noise. When using the socket, insert the parts in the correct position (TH1: between pins 1 and 16, TH2: between pins 3 and 14, RS: between pins 5 and 12, CS: between pins 7 and 10). The connecting pins and socket pins have approximatelys 10 pF stray capacitance. Furthermore, the measurement results may differ from those of the actual IC because the characteristics of the parts used for R/F conversion are different. In particular, pay attention when the software uses an MSB or LSB area in the measurement counter.

(available only when S5U1C62N51E1 is set for the S1C62N51, 60N02 or 60N05)

Note: The S5U1C62N51E1 has an external power input connector for +5 V (VDD) and GND (VSS). Leave these

connectors unconnected when the S5U1C62N51E1 is connected to the ICE.

4.2 Power Cable Connection

When using the S5U1C62N51E1 on its own, it must be supplied with power (5 V DC, 3 A or more) from an external source through the power cable. When the S5U1C62N51E1 is connected to the ICE, power is supplied by the ICE; therefore, the power cable is not necessary. Disconnect the power cable if it is already connected. Figure 4.2.1 shows the connection of the power cable pins.

5.1 Preparation

This section describes the common preparation work necessary when the S5U1C62N51E1 is used by itself and when it is connected to the ICE. Before doing the following, be sure to turn the POWER switch of the S5U1C62N51E1 off.

5.1.1 Creation of target system

Mount the LCD panel, keys, and switches on the board to build a target system. Use the I/O connector and LCD connector supplied with the S5U1C62N51E1 to connect the S5U1C62N51E1 to the target system. (For the pin layout of each connector, refer to Section 3.3, "S5U1C62N51E1 I/O and LCD Connectors".)

Note: There is some difference in specifications between the S5U1C62N51E1 and the actual CPU. Refer to Section

6.2, "Differences from Actual IC" when building a target system.

5.1.2 Creation and installation of ROMs

Create the program ROMs, function option ROM and segment option ROM, and insert them into the sockets of the S5U1C62N51E1.

• Program ROMs (two)

The program ROMs contain the application program machine code. Write the HEX files output by the ASM62N51, 6S3N7, 60N01, 60N02, 60N05 cross-assembler for S5U1C62N51E1 into EPROMs to create program ROMs. Since two HEX files containing the high-order section (C251XXXH.HEX*) and the low-order section (C251XXXL.HEX*) of the machine code are output, two ROMs are created. Insert them into the socket H.HEX and L.HEX under the top cover, respectively. These ROMs are not necessary when connecting the S5U1C62N51E1 to the ICE. In addition, it is necessary to write the object data into the EPROM attaching the offset address as Table 5.1.2.1 according to the type of EPROM that is used.

Table 5.1.2.1 Offset address

EPROM type Offset value

27C64 0000H (without offset) 27C128 0000H (without offset) 27C256 4000H 27C512 C000H

• Function option ROM (one)

The function option ROM is used to specify function options, such as I/O ports. Create the option ROM from the function option HEX file (C251XXXF.HEX*) output by the function option generator, and insert it into the F.HEX socket under the top cover. This ROM is effective even when the ICE is connected, however, this ROM is disregarded due to the loading of the data from the ICE.

• Segment option ROM (one)

The segment option ROM is used to specify segment output port. Create the segment ROM from the segment option HEX file (C251XXXS.HEX*) output by the segment option generator, and insert it into the S.HEX socket in the top cover. This ROM is effective even when the ICE is connected, however, this ROM is disregarded due to the loading of the data from the ICE.

• EPROM specifications

Use EPROMs with the following specifications:

Program ROM: 27C64 to 27C512 (250 ns or less access time) Function option ROM: 27C64 to 27C512 (250 ns or less access time) Segment option ROM: 27C64 to 27C512 (250 ns or less access time)

*"C2

51XXX" is an example when set for the S1C62N51.

5. OPERATION METHOD OF S5U1C62N51E1

5.2 Independent Use of S5U1C62N51E1

This section describes operation when using the S5U1C62N51E1 by itself. The S5U1C62N51E1 may be used independently by connecting a power supply to it. Use a 5 V DC regulator (more than 3 A) as an external power supply. Connect it with the correct polarity (+ and -). (Refer to Section 4.2, "Power Cable Connection".)

5.2.1 Power on/off

Before turning the POWER switch of the S5U1C62N51E1 on, confirm the following: (1) The power cable is connected correctly.

(2) The target system is connected correctly. (3) The ROMs have been installed correctly.

After confirming the above items, turn the POWER switch of the S5U1C62N51E1 on using the following procedure:

(1) Turn the regulator on. If the regulator is a variable-voltage type, set the output voltage to 5 V ±10%. (2) Turn the POWER switch of the S5U1C62N51E1 on.

5.2.2 Debugging

When the S5U1C62N51E1 is used alone, it provides the following debugging function. The method of operation is given below.

• Program free run

When the RESET switch (under the top cover) is pressed, the S5U1C62N51E1 enters the program run state, and executes the application program from page 1, step 0.

5.3 Operation When ICE is Connected

This section explains the operation and use of the S5U1C62N51E1 when it is connected to the ICE. Set up the S5U1C62N51E1 as follows when it is connected to the ICE:

(1) Do not connect the power supply. (2) Keep on turning the POWER switch off.

5.3.1 Power on/off

Power to the S5U1C62N51E1 is supplied by the ICE, and the power is switched on and off by pressing the POWER switch of the ICE. Keep the POWER switch of the S5U1C62N51E1 off.

5.3.2 Debugging

Debugging is done with the host computer, and the S5U1C62N51E1 is controlled by the ICE. For the method of operation, refer to the development tool manual for the S1C62N51, 6S3N7, 60N01, 60N02 or 60N05. The S5U1C62N51E1 can control the following two functions:

(1) RESET switch (2) OSC1 CR oscillation frequency adjustment

6. PRECAUTIONS

Take the following precautions when using the S5U1C62N51E1:

6.1 Precautions for Operation

• Be sure to use the Development Tool that supports the S5U1C62N51E1. Development Tools for the EVA6251, 6S37, 6001, 6002 and 6005 must never been used.

•Turn the power of all equipment off before connecting or disconnecting cables.

•To turn the POWER switch of the S5U1C62N51E1 off, then on again, wait for at least 10 seconds after turning off before turning on.

• When ROMs are inserted into the ROM sockets, lock the lever securely by positioning it horizontally. After the ROMs have been removed from the sockets, lock the lever at the same position above. If the lever is left upright, poor contact may result.

• Confirm that the following ROMs have been installed correctly, then operate the S5U1C62N51E1.

(Top panel) Program ROM 2 L.HEX, H.HEX (Under top cover) Function option ROM 1 F.HEX (Under top cover) Segment option ROM 1 S.HEX

•When developing and debugging the program by connecting the S5U1C62N51E1 to the ICE, the S5U1C62N51E1 reset switch and the target board cannot reset the CPU while the ICE is in monitor status. In this case, reset the CPU by executing the "I" command from the ICE. In Run status, resetting by the S5U1C62N51E1 or target board will be accepted.

6.2 Differences from Actual IC

There are some differences in functions between the S5U1C62N51E1 and the actual IC.

■ I/O

• The response time has been changed by the differences in logic level, output drive capability, and pull-down resistance. The minimum operating voltage is also different from the actual IC.

•When the segment terminals are set to DC output, the output signals are delivered with 0 V and +5 V ±10%.

■ LCD

• The output drive capability is different.

• When the S5U1C62N51E1 is set for the S1C62N51, the LCD drive voltages are set at V and V

L3 = 3.0 V.

L1 = 1.0 V, VL2 = 2.0 V

When the S5U1C62N51E1 is set for the S1C6S3N7, 60N01, 60N02 or 60N05, the LCD drive voltages can be selected from the following three types by function option:

1) V

L1 = 1.0 V, VL2 = 2.0 V, VL3 = 3.0 V

2) V

L1 = 1.5 V, VL2 = 3.0 V, VL3 = 4.5 V

3) V

L1 = VL2 = 1.5 V, VL3 = 3.0 V

However, external voltage cannot be supplied from outside of the S5U1C62N51E1 even when "external power" is selected for the LCD power supply. The S5U1C62N51E1 generates the LCD drive voltage inside and outputs it to the LCD panel.

■ Oscillation circuit

• The type of OSC1 oscillation circuit can be set by function option as follows:

32.768 kHz crystal oscillation or 30 kHz to 90 kHz CR oscillation The CR oscillation clock frequency can be adjusted using the OSC1 ADJ control mounted on the board.

10 EPSON S5U1C62N51E1 MANUAL (Rev.1.0)

Page 15

6. PRECAUTIONS

• The oscillation start and stop times are different from those of the IC. Because the logic level of S5U1C62N51E1 is higher than it of the actual IC.

■ R/F converter (when set for the S1C62N51, 60N02 or 60N05 is selected by function option)

• The CR oscillation characteristics are different from those of the actual IC because the operating voltage and parts of the oscillation circuit are different.
