When changing the CPU operation mode (from NORMAL to SLOW) while the high-fre-
quency oscillation clock (HCLK) or the prescaler output (TMnPSC) is selected as a clock
source, stop the timer before the mode transition. After the mode transition, activate the timer
again. In the SLOW/HALT1 mode, do not select HCLK or any clock generated from HCLK as
a timer clock source.
