12.1
External reset (RES)
After power-on a reset pulse must be applied immediately to the chip, as it is in an undefined state. A reset of the chip
can be achieved using the external reset pad. After the reset the LCD driver is set to the following states:
Power-down mode (PD = 1)
All LCD outputs at V
SS
(display off)
Horizontal addressing (V = 0)
Normal instruction set (H = 0)
Normal display (MX = MY = TRS = BRS = 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)
V
LCD
is equal to 0, the HV generator is switched off (V
op
[6:0] = 0 and PRS = 0)
After power-on (RAM data is undefined), the reset signal does not change the content of the RAM.
