* 1. The voltage deviation is the difference between the output voltage and the segment or common output
desired value (VLCDn; n = 0, 1, 2).
2. Current which flows in the on-chip pull-up resistor or LCD split resistor is not included.
3. Including oscillation of the subsystem clock.
4. When PCC is set to 0000 and the device is operated in the low-speed mode.
5. When the system clock control register (SCC) is set to 1001 and the device is operated on the subsystem
clock, with main system clock oscillation stopped.
