ter and the timer register 1A (TC1DRA) value is detected, an INTTC1 interrupt is generated and the up-coun-
ter 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-cap-
ture function in the operative condition of TC1. A captured value may not be fixed if it's read after the execu-
tion 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.

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