10.3 Function
In the timer mode, the up-counter counts up using the internal clock. When a match between the up-counter and the timer
register 1A (TC1DRA) value is detected, an INTTC1 interrupt is generated and the up-counter is cleared. After being
cleared, the up-counter restarts counting. Setting TC1CR<ACAP1> to “1” captures the up-counter value into the timer reg-
ister 1B (TC1DRB) with the auto-capture function. Use the auto-capture function in the operative condition of TC1. A cap-
tured value may not be fixed if it's read after the execution of the timer stop or auto-capture disable. Read the capture value
in a capture enabled condition. Since the up-counter value is captured into TC1DRB by the source clock of up-counter after
setting TC1CR<ACAP1> to "1". Therefore, to read the captured value, wait at least one cycle of the internal source clock
before reading TC1DRB for the first time.

measurement, programmable pulse generator output modes.
Table 10-1 Internal Source Clock for TimerCounter 1 (Example: fc = 16 MHz, fs = 32.768 kHz)
TimerCounter 1 has six types of operating modes: timer, external trigger timer, event counter, window, pulse width

Example 1 :Setting the timer mode with source clock fc/2
Example 2 :Auto-capture
Note: Since the up-counter value is captured into TC1DRB by the source clock of up-counter after setting TC1CR<ACAP1> to "1".
Therefore, to read the captured value, wait at least one cycle of the internal source clock before reading TC1DRB for the first
time.
