11.2.2
The compare match timer control/status register (CMCSR) is a 16-bit register that indicates the
occurrence of compare matches, sets the enable/disable of interrupts, and establishes the clock
used for incrementation. It is initialized to H'0000 by power-on resets.
Note: The only value that can be written is a 0 to clear the flag.

Bits 15–8 and 5–2—Reserved: These bits always read as 0. The write value should always be
0.
Bit 7—Compare Match Flag (CMF): This flag indicates whether or not the CMCNT and
CMCOR values have matched.
Bit 6—Compare Match Interrupt Enable (CMIE): Selects whether to enable or disable a
compare match interrupt (CMI) when the CMCNT and CMCOR values have matched (CMF =
1).
