10.2.1
The timer 2 control/status register (T2CSR) is a 16-bit readable/writable* register that selects the
clock to be input to the timer 2 counter (T2CNT) and controls compare match interrupts (CMI).
T2CSR is initialized to H'0000 by a power-on reset.

Note: When T2CNT and T2COR still contain their initial values (when the initial values have not
Bits 15 to 7—Reserved: These bits always read 0 and must only be written with 0.
Bit 6—Compare Match Flag (CMF): Status flag that indicates a match between the values of
T2CNT and T2COR. The setting and clearing conditions for this flag are shown below.

been changed or when the T2CNT value has not been incremented), CMF is not set even
though the T2CNT and T2COR values are the same (H'0000).
