Compare Match Timer Control/Status Register 0 (CMCSR0)
The compare match timer control/status register 0 (CMCSR0) is a 16-bit register that indicates the
occurrence of compare matches, sets the enable/disable status of interrupts, and establishes the
clock used for incrementation. It is initialized to H'0000 by a reset, but retains its previous value in
standby mode.
Note: * The only value that can be written is 0 to clear the flag.
Bits 15 to 8 and 5 to 2—Reserved: These bits are always read as 0. The write value should
always be 0.
Bit 7—Compare Match Flag (CMF): Indicates whether or not the compare match timer counter
0 CMCNT0 and compare match timer constant 0 (CMCOR0) values match.
