Table 10-1 Internal Clock Source for Compare Timer/Counter 1 (Example: fc = 20 MHz)
Compare timer/counter 1 has three modes: timer, event counter, and programmable pulse generator output modes.

Function
counter value and the set value of Compare Timer Register 1A (CTC1DRA) match, an INTCTC1 interrupt is
generated and the counter is cleared. After the counter is cleared, it restarts and continues counting up.
CTC1CK
In this mode, the timer/counter (16-bit counter) counts up synchronously with the internal clock. When the

Note:If the CTC input port (P47) is set for input mode, the timer/counter is reset by an input edge on port.
When using the timer/counter as an ordinary timer, set CTC1CR2<EXTRGDIS> to 1 or set P47 for output
mode.
