10.3.1
When a clock is selected with bits CKS2–CKS0 in the T2CSR register, the T2CNT counter starts
incrementing on the selected clock. When the T2CNT counter value matches the value in the timer
2 constant register (T2COR), the T2CNT counter is cleared to H'00, and the CMF flag is set to 1
in the T2CSR register. If the CMIE bit in T2CSR is set to 1 at this time, a compare match interrupt
(CMI) is requested. The T2CNT counter then starts incrementing again from H'00.
The compare match counter operation is shown in figure 10.2.
10.3.2
Any of seven internal clocks ( /2, /8, /32, /128, /512, /2048, or /4096) divided from the
system clock (CK) can be selected with bits CKS2–CKS0 in T2CSR. The count timing is shown
in figure 10.3.
