Section 16 Compare Match Timer (CMT)
16.3
16.3.1
The CMT starts the operation of the counter by writing a 1 to the STRn bit in CMSTR of a
channel that has been selected for operation. Complete all of the settings before starting the
operation. Do not change the register settings other than by clearing flag bits.
The counter operates in one of two ways.
• One-Shot Operation
Page 556 of 1414
One-shot operation is selected by setting the CMM bit in CMCSR to 0. When the value in
CMCNT matches the value in CMCOR, the value in CMCNT is cleared to H'00000000 and
the CMF bit in CMCSR is set to 1. Counting by CMCNT stops after it has been cleared.
To detect an overflow interrupt, set the value in CMCOR to H'FFFFFFFF. When the value in
CMCNT matches the value in CMCOR, CMCNT is cleared to H'00000000 and bits CMF and
OVF in CMCSR are set to 1.
