Notes: 1. The only value that can be written to the CMF bit in CMCSR0 is 0 to clear the flag.
2. When address tran slation by the MMU does not apply , the address in parentheses
should be used.
11.4.2 Register Descriptions
Compare Match Timer Start Register (CMSTR)
The compare match timer start register (CMSTR) is a 16-bit register that selects whether compare
match counter 0 (CMCNT0) is operated or halted. It is initialized to H '0000 by a rese t, but retains
its prev ious value in st an dby mode.
Bit: 15 14 13 12 11 10 9 8

Bits 15 to 2—Reserved: These bits are always read as 0. The write value should alway be 0.
Bit 1—Reserved: This bit can be read or written. The write value should a lways b e 0.
