7 FUNCTIONAL DESCRIPTION
7.1 LCD supply voltage generator
The LCD supply voltage may be generated on-chip. The V
generator is controlled by two internal 6-bit registers:
LCD
VAand VB. The nominal LCD operating voltage at room temperature is given by the relationship:
V
OP(nom)
= (integer value of register × 0.08) + 1.82
7.1.1 PROGRAMMING RANGES Programmed value: 1 to 63. Voltage: 1.90 to 6.86 V.
T
=27°C.
ref
Values producing more than 6.5 V at operating temperature are not allowed. Operation above this
voltage may damage the device. When programming the operating voltage the V
tolerance and temperature
LCD
coefficient must be taken into account.
Values below 2.2 V are below the specified operating range of the chip and are therefore not allowed.
Value 0 for VAand VB switches the generator off (i.e. VA= 0 in character mode, VB= 0 in icon mode).
Usually register VA is programmed with the voltage for character mode and register VB with the voltage for icon mode.
When V
is generated on-chip the V
LCD
pins should be
LCD
decoupled to VSS with a suitable capacitor.
The generated V temperature compensated. When the V
is independent of VDD and is

and
During direct mode (program DM register bit) the internal V
generator is turned off and the V

is directly connected to V
DD2
. This reduces the current

consumption during icon mode and Mux 1 : 9 (depending on V
The V
value and LCD liquid properties).
DD2
generator ensures that, as long as VDDis in the
LCD
valid range (2.2 to 4 V), the required peak voltage VOP= 6.5 V can be generated at any time.
7.2 LCD bias voltage generator
The intermediate bias voltages for the LCD display are also generated on-chip. This removes the need for an external resistive bias chain and significantly reduces the system current consumption. The optimum value of V
LCD
depends on the multiplex rate, the LCD threshold voltage (Vth) and the number of bias levels. Using a 5-level bias scheme for 1 : 18 maximum rate allows V
LCD
< 5 V for most LCD liquids. The intermediate bias levels for the different multiplex rates are shown in Table 1. These bias levels are automatically set to the given values when switching to the corresponding multiplex rate.

7.3 Oscillator
The on-chip oscillator provides the clock signal for the display system. No external components are required and the OSC pin must be connected to V
DD1
.
7.4 External clock
If an external clock is to be used this input is at the OSC pin. The resulting display frame frequency is given by:
f
=
OSC
------------­3072
f
frame
Only in the Power-down mode is the clock allowed to be stopped (OSC connected to V
), otherwise the LCD is
SS
frozen in a DC state.
7.5 Power-on reset
The on-chip Power-on reset block initializes the chip after power-onor power failure. This isasynchronous reset and requires 3 oscillator cycles to be executed.
7.6 Power-down mode
Thechip can be putinto Power-down mode byapplying an external active HIGH level to the PD pin. In Power-down mode all static currents are switched off (no internal oscillator, no bias level generation and all LCD outputs are internally connected to VSS).
During power-down, information in the RAMs and the chip state are preserved. Instruction execution during power-down is possible when pin OSC is externally clocked.
7.7 Registers
The PCF2113x has two 8-bit registers, an Instruction Register (IR) and a Data Register (DR). The Register Select (RS) signal determines which register will be accessed.The instruction register storesinstruction codes such as ‘display clear’, ‘cursor shift’, and address information for the Display Data RAM (DDRAM) and Character Generator RAM (CGRAM).The instruction register can be written to but not read from by the system controller.
The data register temporarily stores data to be read from the DDRAM and CGRAM. When reading, data from the DDRAM or CGRAM corresponding to the address in the instruction register is written to the data register prior to being read by the ‘read data’ instruction.
7.8 Busy flag
The busy flag indicates the internal status of the PCF2113x. A logic 1 indicates that the chip is busy and further instructions will not be accepted. The busy flag is output to pin DB7 when bit RS = 0 and bit R/
W=1. Instructions should only be written after checking that the busy flag is at logic 0 or waiting for the required number of cycles.
7.9 Address Counter (AC)
The address counter assigns addresses to the DDRAM and CGRAM for reading and writing and is set by the commands ‘set CGRAM address’ and ‘set DDRAM address’. After a read/write operation the address counter is automatically incremented or decremented by 1. The address counter contents are output to the bus (DB6 to DB0) when bit RS = 0 and bit R/W=1.
7.10 Display Data RAM (DDRAM)
The DDRAM stores up to 80 characters of display data represented by 8-bit character codes. RAM locations which are not used for storing display data can be used as general purpose RAM. The basic RAM to display addressing scheme is shown in Fig.3. With no display shift the characters represented by the codes in the first 24 RAM locations starting at address 00H in line 1 are displayed. Figures 4 and 5 show the display mapping for right and left shift respectively.
When data is written to or read from the DDRAM, wrap-around occurs from the end of one line to the start of the next line. When the display is shifted each line wraps around within itself, independently of the others. Thus all lines are shifted and wrapped around together. The address ranges and wrap-around operations for the various modes are shown in Table 2.
Table 2 Address space and wrap-around operation
MODE 1 × 24 2 × 12 1 × 12
Address space 00 to 4F 00 to 27; 40 to 67 00 to 27 Read/write wrap-around (moves to next line) 4F to 00 27 to 40; 67 to 00 27 to 00 Display shift wrap-around (stays within line) 4F to 00 27 to 00; 67 to 40 27 to 00

7.11 Character Generator ROM (CGROM)
The CGROM generates 240 character patterns in a 5 × 8 dot format from 8-bit character codes. Figures 7, 8, 9 and 10 show the character sets that are currently implemented.
7.12 Character Generator RAM (CGRAM)
Up to 16 user defined characters may be stored in the CGRAM. Some CGRAM characters (see Fig.16) are also used to drive icons (6 if icons blink and both icon rows are used in the application; 3 if no blink but both icon rows are used in the application; 0 if no icons are driven by the icon rows). The CGROM and CGRAM use a common address space, of which the first column is reserved for the CGRAM (see Fig.7). Figure 11 shows the addressing principle for the CGRAM.
7.13 Cursor control circuit
The cursor control circuit generates the cursor underline and/or cursor blink as shown in Fig.6 at the DDRAM address contained in the address counter.
When the address counter contains the CGRAM address the cursor will be inhibited.
7.14 Timing generator
The timing generator produces the various signals required to drive the internal circuitry. Internal chip operation is notdisturbed by operations on thedata buses.
7.15 LCD row and column drivers
The PCF2113x contains 18 row and 60 column drivers, which connect the appropriate LCD bias voltages in sequence to the display in accordance with the data to be displayed. R17 and R18 drive the icon rows.
The bias voltages and the timing are selected automatically when the number of lines in the display is selected. Figures 12, 13, 14 and 15 show typical waveforms. Unused outputs should be left unconnected.

Character code bits 0 to 3 correspond to CGRAM address bits 3 to 6. CGRAM address bits 0 to 2 designate the character pattern line position. The 8th line is the cursor position and display is performed by logical ORwith
the cursor. Data in the 8th position will appear in the cursor position. Character pattern column positions correspond to CGRAM data bits 0 to 4, as shown in this figure. As shown in Figs 7 and 8, CGRAM character patterns are selected when character code bits 4 to 7 are all logic 0. CGRAM data = logic 1 corresponds
to selection for display. Only bits 0 to 5 of the CGRAM address are set by the ‘set CGRAM address’ command. Bit 6 can be set using the ‘set DDRAM address’ command in
the valid address range or by using the auto-increment feature during CGRAM write. All bits 0 to 6 can be read using the ‘read busy flag’ and ‘address counter’ command.
Fig.11 Relationship between CGRAM addresses, data and display patterns.

7.16 Reset function
The PCF2113x automatically initializes (resets) when power is turned on. The chipexecutes a reset sequence, including a ‘clear display’, requiring 165 oscillator cycles. After the reset the chip has the state shown in Table 3.
Table 3 State after reset
STEP FUNCTION CONTROL BIT STATE CONDITIONS
