Pin Name
Power supply pins for the controller block.
Normally, V
When only the CPU operates (when the
75-kHz/32.768-kHz oscillator is used), it can
operate at
V
In the backup state (when the CKSTP
instruction is executed), current dissipation
decreases (10 mA or below), allowing the power
supply voltage to be reduced to 1.0 V.
Raising the voltage on MVDD pin from 0 V to
1.8 V or higher triggers a system reset, causing
the program to start from address 0 (power-on
reset).
(Note) At power-on reset operation, allow 1 ms
