9.3.3 TIMER Mode Operation
The TIMER mode controls the interrupt generation and output signal using the counter overflow.
9.3.3.1 Output Waveform in TIMER Mode
The timer output has two kinds of phase, the positive phase and the negative phase.
When writing "1" to the FTnSTR bit of the FTCSTR register with the counter set to "0x0000", the positive phase output
starts with "H" level and the negative phase output starts with "L" level.
Also, when writing "1" to the FTnDTEN bit of the FTnMOD register, after the counting is started, the output remains
"L" level until the count set in the FTnDT register elapses.
In the repeat mode, the output repeats to toggle the signal level synchronizing with the start of count and the overflow.
In the one-shot mode, the positive output remains "H" level for one cycle of the timer and then the count stops. The
negative output is fixed to "L".
Figure 9-3 (a) shows waveforms of the positive phase/negative phase output in the repeat mode.
Figure 9-3 (b) shows waveforms of the positive phase/negative phase output in the one-shot mode.
