Notes 1. Total current flowing through the internal power supply (V

).
2. Includes the peripheral operating current. However, the current flowing through the pull-up resistors
on the ports is not included.
3. When the processor clock control register (PCC) is set to 00H.
4. When PCC is set to 02H.
5. When the main system clock is stopped.
6. When the LCD is stopped (LCDON = 0, SCOC = 0, VLCON = 0).
7. Only when the LCD boost function is operating (LCDON = 0, SCOC = 0, VLCON = 1).
8. When the LCD is operating (LCDON = 1, SCOC = 1, VLCON = 1).
9. With no load and without the LCD display panel connected. Also with capacitors for boost C1 to C4
