10.2.2
The timer 2 counter (T2CNT) is a 16-bit readable/writable register used as an 8-bit up-counter.
T2CNT increments on the internal clock selected by bits CKS2–CKS0 in T2CSR. The T2CNT
value can be read or written by the CPU at all times. When the T2CNT value matches the value in
the timer 2 constant register (T2COR), T2CNT is cleared to H'0000 and the CMF flag is set to 1 in
T2CSR. If the CMIE bit in T2CSR is set to 1 at this time, a compare match interrupt (CMI) is
generated.
Bits 15 to 8 are reserved and have no counter function. These bits always read 0 and must only be
written with 0.
T2CNT is initialized to H'0000 by a power-on reset

Bit 5—Compare Match Interrupt Enable (CMIE): Enables or disables interrupt requests
initiated by the CMF flag when set to 1 in T2CSR.
Bits 4 to 2—Clock Select 2 to 0 (CKS2–CKS0): These bits select one of seven internal clock
sources, obtained by dividing the system clock ( ), for input to T2CNT.
Bits 1 and 0—Reserved: These bits always read 0 and must only be written with 0.
