16.4.2 Store of display data

Generally, display data are prepared as fixed data in program memory (ROM) and stored in display data area

by load command.

Example : To operate a 1/4 duty LCD of 40 segments

× 4 com-mons at frame frequency fc/216 [Hz], and booster fre-

quency fc/213 [Hz]

(LCDCR), 01000001B

; Sets LCD driving method and frame frequency. Boost frequency

(P*LCR), 0FFH

; Sets segment output control register. (*; Port No.)

; Sets the initial value of display data.

(LCDCR), 11000001B

; Display enable

Sets LCD driving method (DUTY).

Sets frame frequency (SLF).

Sets segment output control registers

(P*LCR (*; Port No.))

Initialization of display data area.

Display enable (EDSP)

(Releases from blanking.)

Sets boost frequency (VFSEL).

Enables booster circuit (BRES)
