Read/Write
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: These bits cannot be modified and are always read as 1.
Bits 1 and 0⎯Divide (DIV1, DIV0): These bits select the frequency division ratio, as follows.
