Notes 1. This includes only the current that flows through the watchdog timer (including the operating current of the
240 kHz internal oscillator). When the watchdog timer is operating in HALT mode or STOP mode, the
current value of the 78K0/LC3 is obtained by adding I
WDT to IDD2 or IDD3.
2. This includes only the current that flows through the LVI circuit. When the LVI circuit is operating in HALT
mode or STOP mode, the current value of the 78K0/LC3 is obtained by adding I
LVI to IDD2 or IDD3.
3. This includes only the current that flows through the A/D converter. When the A/D converter is operating
in HALT mode or STOP mode, the current value of the 78K0/LC3 is obtained by adding I
ADC1, IADC2, or
I
ADC3 to IDD1 or IDD2.
4. This includes only the current that flows through the LCD controller/driver. Not including the current that
flows through the LCD divider resistor. The current value of the 78K0/LC3 is obtained by adding the LCD
operating current (I
LCD1 or ILCD2) to the supply current (IDD1, IDD2, or IDD3).
