Voltage Control
Power Supply Control Register 1 (PWCTR1: 0x03F6D)
The power supply control register 1 controls CPU outage when changing the output voltage, VDD18 and Deep
STANDBY mode.
..
Set the PWCTR1.PWUPTM2-0 to match the following conditions before the transition from
1.1 V to 1.8 V or to 1.3 V.
- From 1.1 V to 1.8 V: 500
µ
s or more
- From 1.1 V to 1.3 V: 4 ms or more
..
..
* Only the clock supplied to CPU is halted.
The clock supplied to peripheral function is not halted. Stop the clock for each function.
