Notes 1. The port current (including the current that flows to on-chip pull-up resistors) 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 LCD is not operating and the booster circuit is operating (LCDON0 = 0, VAON0 = 1, LIPS0 = 1).

5. When the main system clock is stopped

6. When the LCD is not operating (LCDON0 = 0, VAON0 = 0, LIPS0 = 0)

7. Then the LCD is operating (LCDON0 = 1, VAON0 = 1, LIPS0 = 1)

8. This is the total current that flows to V

DD

and AV

.

Remark Unless otherwise specified, the characteristics of alternate-function pins are the same as those of port

pins.
