Note 4: Auto-capture can be used only in the timer, event counter, and window modes.

Note 5: To set the timer registers, the following relationship must be satisfied.

TC10DRA > TC10DRB > 1 (PPG output mode), TC10DRA > 1 (other modes)

Note 6: Set TFF10 to “0” in the mode except PPG output mode.

Note 7: Set TC10DRB after setting TC10M to the PPG output mode.

Note 8: When the STOP mode is entered, the start control (TC10S) is cleared to “00” automatically, and the timer stops. After the

STOP mode is exited, set the TC10S to use the timer counter again.

Note 9: Use the auto-capture function in the operative condition of TC10. 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.

Note 10:Since the up-counter value is captured into TC10DRB by the source clock of up-counter after setting TC10CR<ACAP10>

to "1". Therefore, to read the captured value, wait at least one cycle of the internal source clock before reading TC10DRB

for the first time.

8.1.3 Function

TimerCounter 10 has six types of operating modes: timer, external trigger timer, event counter, window,

pulse width measurement, programmable pulse generator output modes.

8.1.3.1 Timer mode

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

cleared, the up-counter restarts counting. Setting TC10CR<ACAP10> to “1” captures the up-counter value into the timer

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 TC10DRB by the source clock of up-

counter after setting TC10CR<ACAP10> to "1". Therefore, to read the captured value, wait at least one cycle of the internal

source clock before reading TC10DRB for the first time.
