16.3.2
In this module, the size of the counter is selectable as either 16 or 32 bits. This is selected by the
CMS bit in CMCSR.
When the 16-bit size is selected, use a 32-bit value which has H'0000 as its upper half to set
CMCOR.
To detect an overflow interrupt, the value must be set to H'0000FFFF.

Free-running operation is selected by setting the CMM bit in CMCSR to 1. When the value in
CMCNT matches the value in CMCOR, CMCNT is cleared to H'00000000 and the CMF bit in
CMCSR is set to 1. CMCNT resumes counting-up after it has been cleared.
To detect an overflow interrupt, set CMCOR to H'FFFFFFFF. When the values in CMCNT
and CMCOR match, CMCNT is cleared to H'00000000 and bits CMF and OVF in CMCSR
are set to 1.
