CHAPTER 3: JUMPERS

3.1 Clock Multiplier select (JP1)

The clock multiplier selection jumper sets the clock frequency multiplier for the MZ-6SER core.
Each setting will put the MZ-6SER core at a different operating speed.

The CPU operating speed is determined by the CPU clock (33MHz or 64MHz) multiplied by
the CPU frequency ratio.

- Refer to section 3.6 for setting CPU clock

- For example, using 2X ratio, the CPU speed will be (2x64) = 128 MHz

Table 2: Clock Multiplier Select (JP1)

CPU Freq ratio

1X
2X

*Factory default setting
**The maximum rated speed of the ZFx86 processor is 128MHz. Avoid
using combinations of CPU Freq ratio and Oscillator frequency that results
in over clocking the ZFx86. Over clocking will void the warranty.

3.3 Write Enable Jumper for Bios Flash (JP2)

Install jumper shunt on JP2 to enable writing to the Bios Flash chip. The Bios chip is a
512Kbyte device with the Bios located at 40000H to 7FFFFH. Locations from 0 to 3FFFFH are
available for the customers use.

- Remove the jumper shunt on JP2 to write protect the Bios Flash. This will allow
read only accesses.

3.4 Watchdog Timer (JP3)

The MZ-6SER has two watchdog timers, WD1 and WD2. Both timers are programmable.
WD1 counter expires in 2 seconds and WD2 in 7ms. WD2 starts counting down after WD1
expires. When WD2 counter reaches zero, it will unconditionally cause a system reset.

The watchdog timer alarms if not triggered by the system or application at least once every 2
seconds. If the watchdog timer does not receive a reset “tickle” when 2 seconds has elapsed,
it generates an alarm signal. The watchdog timer alarm is reset “tickled” by toggling the WDI
signal or writing to index 0x10h of the ZF-Logic I/O space. The watchdog is triggered
continuously (disabled) if jumper shunt JP3 [2-3] is installed. This arrangement allows
watchdog input (WDI) to be toggled by the watchdog alarm output (WDO) in a self-triggering
fashion. If a jumper shunt JP3 [1-2] is installed, the watchdog will be triggered by an external
signal or event from pin5 of CN8.

The watchdog timer alarm signal (WDO) can be programmed to generate the following
response when the corresponding bit is set at the watchdog control register in the ZF-Logic I/O
space.

3.7 CPU Core Voltage Select (JP6)

At a CPU speed of 128 MHz, the core voltage must be set for 2.75 volts. At frequencies below
128 MHz, the core voltage should be lowered to conserve power, and to reduce the dissipated
heat. Jumper JP6 allows for three possible core voltages of 2.75 volts, 2.5 volts and 2.25
volts.

3.9 RS485 Half/Full Duplex Mode Select (JP8)

Jumper JP8 routes the RS485 signals to setup half or full duplex operation. When half duplex
operation is setup, communication for the RS485 port five is routed to serial ports five, and
communication for the RS485 ports six is routed to serial port six. When full duplex mode is
selected the RS485 receive signal is routed to the RS485 port six.

4.1 Serial Interfaces (CN1 to CN6)

The MZ-6SER provides six PC-compatible asynchronous serial ports. All six serial ports have
RS232 drivers. Serial port five and serial port six are jumper configurable as half duplex
RS485 ports. Serial port six can be configured as a full duplex RS485 (with serial port five in
RS232 mode only). Serial RS232 ports connectors are grouped in sets of two. That is, Serial
1 (CN1) and Serial 2 (CN2) connectors are adjacent to each other creating a 10 pin by 2 pin
header. Similarly, serial 3 (CN3) and serial 4 (CN4) are adjacent, and serial 5 (CN5) and serial
6 (CN6) are adjacent. RS485 signals are available on connector CN7.

All six serial ports supply full complements of input and output handshaking lines. These
signals are at standard RS232C levels. The RS232C level converters provide the required
RS232C voltage levels with internal +5 volt to ±9 volt converters. The serial port drivers have

an automatic power down mode that turns off the driver outputs. This occurs whenever there
isn't a valid signal level on any of the receive pins on the driver chip.

Serial port one and Serial port two can be disabled using BIOS SETUP. The IOCS (I/O chip
select) signals the quad UART uses for Serial ports 3 to 6 can be disabled through the BIOS
SETUP. When disabled, the port’s I/O address is made available for other expansion devices
on the 16-bit BUS.

4.7 Parallel (CN13)

The MZ-6SER parallel port is fully compatible with the PC/AT parallel port. In the extended
mode, it functions as a PS/2-like bi-directional port. In Extended Capabilities Port (ECP) mode,
it is IEEE 1284 compliant, including level 2.

The parallel ports uses the following PC resources when enabled:

Table 23: Parallel Port Resources

Parallel Port Typical Usage I/O Address Standard Interrupt

Parallel 1 LPT1 378H – 37Fh IRQ7

The default interrupt for parallel port LPT1 is IRQ7. The parallel port output signals provide up
to 14-mA drive current. RC filters are provided for noise suppression. The parallel port signals
appear on CN13, a dual-row ribbon-cable pin edge connector. The port may be cabled to
appear on a standard PC DB-25 connector. A DB-25 connector and cable are provided for this
purpose in the optional MZ-6SER cable kit. The following table shows the parallel port signals
appearing on CN13 and the equivalent pin out on a DB-25 connector.

24/04/2003 MZ-6SER Manual

CHAPTER 5: BIOS SETTINGS

5.1 BIOS Setup

The MZ-6SER system BIOS (Basic Input Output System) supports a standard SETUP function
to configure system parameters. The BIOS uses these parameters to establish default
conditions during system initialization, both during the Power On Self Test (POST) phase, and
during system boot.

Using SETUP

To enter the SETUP function, press the <F2> key during POST.

Note: When you change SETUP parameters, the new values do not take effect until
the system is rebooted.

For details about how to set the various parameters using SETUP, please refer to the MachZ
BIOS Users Manual Supplement and the Phoenix BIOS 4.0 Rev 6 manual.

Customizing BIOS CMOS default

The CMOS default settings of the MZ-6SER can be customized by using the ZEB and
AMDFLASH utilities from ZFMicro. www.zflinux.com

The ZEB utility allows the majority of the CMOS parameters to be set to a particular value
which become the default settings when the MZ-6SER is powered up. ZEB modifies a BIOS
image file which is then programmed into the flash device using AMDFLASH utility. Please
note that setting the CMOS defaults is different from changing the CMOS settings. The CMOS
default settings only become effective when there is a no backup battery provided or when the
CMOS settings are cleared.

APPENDIX 1: OPTIONAL MZ104+UTIL UTILITY BOARD

The MZ104+UTIL Utility Board, (see Figure 3) provides a convenient means to connect
peripheral devices to the MZ-6SER embedded CPU module. In addition, the MZ104+UTIL
provides input/output functionality of a status LED, and a hardware-reset switch. For
applications requiring a GPS receiver, the Utility Board also acts as carrier board to mate with
several models of Royaltek GPS receivers available from Tri-M Systems.

The MZ104+UTIL interfaces to the MZ-6SER CPU module via three ribbon cables and one
flex-foil cable. The MZ104+UTIL can be mounted above the MZ-6SER with PC/104 stand offs.
