- Capacitor which is mounted on user system when LCD controller/driver is used
The following capacitors are mounted on QB-RL78L1C internal circuit.
Because of this, terminal characteristic on QB-RL78L1C is slightly different from target device.
Mounting point: Between VL1 and GND terminals, Between VL2 and GND terminals,
Between VL3 and GND terminals, Between VL4 and GND terminals,
Between CAPH and CAPL terminals
Mounted condenser capacity: 0.1uF
- LCD controller/driver behavior
When executing STOP instruction or an instruction which stops the main system clock (fMAIN) with setting the
main system clock (fMAIN) to an operation clock of LCD controller/driver, LCD controller/driver stops execution
on target device. On the other hand, it continues execution on QB-RL78L1C.
- Port function of pin LCD alternate function pin
When using LCD alternate function pin as port function, pin status becomes high impedance for 6.5 ms after the
port mode register (PMn) setting and the LCD port function register (PFSEGm) setting.
