Notes 1. The port current (including the current that flows to the on-chip pull-up resistor) is not included.
2. High-speed mode operation (when the processor clock control register (PCC) is set to 00H)
3. Low-speed mode operation (when PCC is set to 02H)
4. When the main system clock is stopped
5. This is the current 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 I
DD2
(HALT mode).
6. When the LCD voltage amplifier is stopped (LCDON0 = 0, VAON0 = 0)
7. This is the total current that flows to V
DD
and AV
DD
.
Remark Unless otherwise specified, the characteristics of alternate-function pins are the same as those of port
pins.
