10.Scroll control
SN2–SN0 = 000: First line displayed at the top
SL2–SL0 = 000: First raster-row displayed at the top of the first line
11.Annunciator control
DA = 0: Annunciator display off
12.Key scan control
IRE = 0: Key scan interrupt (IRQ*) generation disabled
KF1, KF0 = 00: Key scan cycle set to 320 clock cycles
13.LED/general port
LED2/LED1/LED0 = 000: LED2/LED1/LED0 outputs = V
CC
level
PORT2/ PORT1/ PORT0 = 000: PORT2/ PORT1/ PORT0 outputs = GND level
14.LCD driver output direction
CMS = 0: Starts shift from COM1/32
SGS = 0: Starts shift from SEG1/60
RAM data initialization:
1. DDRAM
All addresses are initialized to 20H by the clear display instruction
2. CGRAM/SEGRAM
Not automatically initialized by reset input; must be initialized by software while display is off (D = 0)
3. Annunciator data
Not automatically initialized by reset input; must be initialized by software while display is off (DA= 0)
Output pin initialization:
1. LCD driver output pins (SEG/COM, ASEG/ACOM): Outputs V
CC
level
2. Booster output pins (V5OUT2 and V5OUT3): Outputs GND level
3. Oscillator output pin (OSC2): Outputs oscillation signal
4. Key strobe pins (KST0 to KST7): Outputs strobe signals at a specified time interval
5. Key scan interrupt pin (IRQ*): Outputs V
CC
level
6. LED driving port (LED0–LED2): Outputs V
CC
level
7. General output port (PORT0–PORT2): Outputs GND level
