Control Register 1 (R0):
Control register 1 (figure 26) controls general operations of the HD66420. Each
bit has its own function as described below.
RMW bit
RMW = l: Read-modify-write mode Address is incremented only after write access
RMW = 0: Address is incremented after both write and read accesses
DISP bit
DISP = 1: Display on
DISP = 0: Display off (all LCD driver output pins output VLCD level)
STBY bit
STBY = l: Internal operation and oscillation halt; display off
STBY = 0: Normal operation
PWR bit
PWR = l: Output high level from DCON terminal
PWR = 0: Output low level from DCON terminal
This bit controls the external power supply for LCD driving outputs.
AMP bit
AMP = 1: OP amp enable
AMP = 0: OP amp disable
REV bit
REV = 1: Reverse display
REV = 0: Normal display
HOLT bit
HOLT = l : Internal operation stops
HOLT = 0: Internal operation starts
ADC bit
ADC = l: Data in X address H’0 is output from SEG160; row signals depend on duty.
ADC = 0: Data in X address H’0 is output from SEG1; row signals are scanned from COM1.
