Notes 1. Current flowing only to the real-time counter. The current value of the 78K0/Kx2-L microcontrollers is the sum
of I
DD1, IDD2 or IDD3 and IRTC when the real-time counter operates.
2. Current flowing only to the watchdog timer (including the operating current of the 30 kHz internal oscillator).
The current value of the 78K0/Kx2-L microcontrollers is the sum of I
DD1, IDD2 or IDD3 and IWDT when the
watchdog timer operates.
3. Current flowing only to the 8-bits timer H1. The current value of the 78K0/Kx2-L 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).
4. Current flowing only to the LVI circuit. The current value of the 78K0/Kx2-L microcontrollers is the sum of I
DD1,
I
DD2 or IDD3 and ILVI when the LVI circuit operates.
5. Current flowing only to the A/D converter (AVREF). The current value of the 78K0/Kx2-L 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.
6. Current flowing only to the operational amplifier (AV
REF or VDD). The current value of the 78K0/Kx2-L
microcontrollers is the sum of I
DD1 or IDD2 and IAMP when the operational amplifier operates in an operation
mode or the HALT mode.
