Function
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 register 1B (TC1DRB) with the auto-capture function. Use the auto-capture function
in the operative condition of TC1. A captured 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.

In the timer mode, the up-counter counts up using the internal clock. When a match between the up-counter

Note:Since the up-counter value is captured into TC1DRB by the source clock of up-counter after setting
