Notes 1. Current flowing only to the watchdog timer (including the operating current of the 30 kHz internal oscillator).
The current value of the 78K0/Ix2 microcontrollers is the sum of I
DD1, IDD2 or IDD3 and IWDT when the watchdog
timer operates.
2. Current flowing only to the 8-bits timer H1. The current value of the 78K0/Ix2 microcontrollers is the sum of
I
DD1, IDD2 or IDD3 and ITWH when the 8-bits timer H1 operates (When using the 30 kHz internal low-speed
oscillation clock as the count clock).
3. Current flowing only to the LVI circuit. The current value of the 78K0/Ix2 microcontrollers is the sum of I
DD1,
I
DD2 or IDD3 and ILVI when the LVI circuit operates.
4. Current flowing only to the A/D converter (AV
REF). The current value of the 78K0/Ix2 microcontrollers is the
sum of I
DD1 or IDD2 and IADC when the A/D converter operates in an operation mode or the HALT mode.
5. Current flowing only to the operational amplifier (AV
REF). The current value of the 78K0/Ix2 microcontrollers is
the sum of IDD1 or IDD2 and IAMP when the operational amplifier operates in an operation mode or the HALT
mode.
6. Current flowing only to the comparator (AV
REF). The current value of the 78K0/Ix2 microcontrollers is the sum
of IDD1 or IDD2 and ICMP when the comparator operates in an operation mode or the HALT mode.
