• LCD RAM capacity
8 bits × 13 bytes (104 bits)
• Word access to LCD RAM
• The segment output pins can be used as ports.
SEG24 to SEG1 pins can be used as ports in groups of four.
• Common output pins not used because of the duty cycle can be used for common double-
buffering (parallel connection).
With 1/2 duty, parallel connection of COM1 to COM2, and of COM3 to COM4, can be used
In static mode, parallel connection of COM1 to COM2, COM3, and COM4 can be used
• Choice of 11 frame frequencies
• A or B waveform selectable by software
• On-chip power supply split-resistance
Removal of split-resistance can be controlled in software. Note that this capability is
implemented in the H8/38104 Group only.
• Display possible in operating modes other than standby mode
• Use of module standby mode enables this module to be placed in standby mode independently
when not used. (For details, refer to section 5.4, Module Standby Function.)
