Setting of starting counting and interrupt
0
Timer interrupt is not generated when counting is started
(timer output does not change, either).
• Interval timer mode
(0, 0, 0)
• Capture mode
(0, 1, 0)
1
Timer interrupt is generated when counting is started
(timer output also changes).
• Event counter mode
(0, 1, 1)
0
Timer interrupt is not generated when counting is started
(timer output does not change, either).
0
Start trigger is invalid during counting operation.
At that time, interrupt is not generated, either.
• One-count mode
Note 1
(1, 0, 0)
1
Start trigger is valid during counting operation
Note 2
.
At that time, interrupt is also generated.
• Capture & one-count mode
(1, 1, 0)
0
Timer interrupt is not generated when counting is started
(timer output does not change, either).
Start trigger is invalid during counting operation.
At that time interrupt is not generated, either.
Other than above Setting prohibited
Notes 1. In one-count mode, interrupt output (INTTMmn) when starting a count operation and TOmn output are
not controlled.
2. If the start trigger (TSmn = 1) is issued during operation, the counter is initialaized, an interrupt is
generated, and recounting is started.
Remark m: Unit number (m = 0, 1), n: Channel number (n = 0 to 7)
