by the TC2CR<TC2CK>.
In this mode, events are counted on the rising edge of the TC2 pin input. The contents of TC2DR are com-
Match detect is executed on the falling edge of the TC2 pin. Therefore, an INTTC2 interrupt is generated at
The minimum input pulse width of TC2 pin is shown in Table 9-2. Two or more machine cycles are required
In this mode, counting up performed on the rising edge of an internal clock during TC2 external pin input
The maximum applied frequency (TC2 input) must be considerably slower than the selected internal clock
Note:It is not available window mode in the SLOW/SLEEP mode. Therefore, at the window mode in NORMAL
mode, the timer should be halted by setting TC2CR<TC2S> to "0" before the SLOW/SLEEP mode is entered.
