Notes 1. Total current flowing into the internal power supply (V
(however, the current flowing into the pull-up resistors of the port, and A/D converter is not included).
2. Square-wave input
3. When AMPH (bit 0 of clock operation mode select register (OSCCTL)) = 0.
4. When main system clock is stopped
5. Total current flowing into the internal power supply (V
(however, the current flowing into the pull-up resistor of the port, A/D converter, watchdog timer, and LVI
circuit is not included)
6. Current flowing only to the A/D converter. The current value of the 78K0/KE2 is the sum of I
and I when the A/D converter operates in an operation mode or the HALT mode.
ADC
7. Current flowing only to the watchdog timer. The current value of the 78K0/KE2 is the sum of I
and I when the watchdog timer operates in the HALT or STOP mode.
WDT
8. Current flowing only to the LVI circuit. The current value of the 78K0/KE2 is the sum of I
when the LVI circuit operates in the HALT or STOP mode.
