Table 2
Explanations for symbols in Table 1
External reset (RES)
After power-on a reset pulse has to be applied immediately to the chip, as it is in an undefined state. A reset of the chip
can be achieved with the external reset pin. After the reset the LCD driver is set to the following status:
Power down mode (PD = 1)
All LCD-outputs at V
SS
(display off)
Read-modify-write mode is disabled (RM = 0)
Horizontal addressing (V = 0)
Normal instruction set (H = 0)
Normal display (MX = MY = 0)
Display blank (E = D = 0)
Address counter X[6 : 0] = 0 and Y[3 : 0] = 0
Temperature coefficient (TC[1 : 0] = 0)
Bias system (BS[2 : 0] = 0)
Read-modify-write mode disabled (RM = 0)
V
LCD
is equal to 0, the HV generator is switched off (V
OP
[6 : 0] = 0)
After power-on, RAM data are undefined; The reset signal does not change the content of the RAM.
Set read-modify-write
When RM = 0, the read-modify-write mode is disabled. The X/Y-address counter is incremented after every read or write
access to the display data RAM.
When RM = 1, the read-modify-write mode is enabled. In this mode the X/Y-address is incremented only after a write
access to the display data RAM. The X/Y-address will not be incremented after a read access to the RAM.
