Interrupts

9.4.1

Interrupt Source

When interrupt request flag CMF is set to 1, and interrupt enable bit CMIE is also 1, the

corresponding interrupt request is output.

9.4.2

Timing of Compare Match Flag Setting

The CMF bit in the T2CSR register is set to 1 by the compare match signal generated when the

T2COR register and T2CNT counter values match. The compare match signal is generated in the

last state in which the match is true (when the value at which the T2CNT counter match occurred

is about to be updated). Therefore, after a match between the T2CNT counter and the T2COR

pulse. Figure 9.4 shows the timing of CMF bit setting.
