Note:
19.5.2
DIVCR is an 8-bit readable/writable register that selects the division ratio of the frequency
divider.
DIVCR is initialized to H'FC by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bits 7 to 2—Reserved: Read-only bits, always read as 1.
Bits 1 and 0—Divide (DIV1 and DIV0): These bits select the frequency division ratio, as
follows.
