4.4.1
FRQCR is a 16-bit readable/writable register that specifies the frequency division ratios for the
internal clock (Iφ), bus clock (Bφ), peripheral clock (Pφ), MTU2S clock (MIφ), and MTU2 clock
(MPφ). FRQCR can be accessed only in words.
FRQCR is initialized to H'36DB only by a power-on reset (except a power-on reset due to a WDT
overflow).
