R/W
Sets the upper 12 bits of the 16 bits of calculation values of the
warming up timer.
About a setup of a warming up timer, refer to the “1.2.4.1The
warming up timer for a high speed oscillation”.

R
Sets the lower 4 bits of the 16 bits of calculation values of the
warming up timer. It is fixed to “0000”.

0: don't care
1: Warming up operation start.
Note1: Use the internal oscillator for warming up when the MCU returns from STOP1 mode. Do not use an
external oscillator when the MCU returns from STOP1 mode.
Note2: Do not modify the registers during the warming up (<WUEF>=1). Set the registers when <WUEF>=0.
