RX23W Group 27. Compare Match Timer (CMT)
27.2.4 Compare Match Counter (CMCNT)
The CMCNT counter is a readable/writable up-counter.
When an frequency dividing clock is selected by the CMCR.CKS[1:0] bits and the CMSTRm.STRn (m = 0, 1; n = 0 to 3)
bit is set to 1, the CMCNT counter starts counting up using the selected clock.
When the value in the CMCNT counter and the value in the CMCOR register match, the CMCNT counter is set to
0000h. At the same time, a compare match interrupt (CMIn) (n = 0 to 3) is generated.
27.2.5 Compare Match Constant Register (CMCOR)
The CMCOR register is a readable/writable register to set a value for compare match with the CMCNT counter.
