The port current (including the current that flows to the on-chip pull-up resistor) is not included.
High-speed mode operation (when processor clock control register (PCC) is set to 00H)
Low-speed mode operation (when PCC is set to 02H)
When the main system clock is stopped
This is the total current that flows when the LCD controller/driver is operating (LCDON0 = 1, VAON0 =
1, LIPS0 = 1). The power supply current when the LCD is not operating (LCDON0 = 0, VAON0 = 1,
LIPS0 = 0) is included in IDD2.
This is the current when the LCD voltage booster circuit is stopped (LCDON0 = 0, VAON0 = 1).
Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of port
pins.
