Section 11 16-Bit Timer Pulse Unit (TPU)
Figure 11.19 illustrates the operation when counting upon TCNT_2 overflow/underflow has been
set for TCNT_1, and phase counting mode has been designated for channel 2.
TCNT_1 is incremented by TCNT_2 overflow and decremented by TCNT_2 underflow.
11.4.5
In PWM mode, PWM waveforms are output from the output pins. 0, 1, or toggle output can be
selected as the output level in response to compare match of each TGR.
Settings of TGR registers can output a PWM waveform in the range of 0% to 100% duty cycle.
Designating TGR compare match as the counter clearing source enables the cycle to be set in that
register. All channels can be designated for PWM mode independently. Synchronous operation is
also possible.
There are two PWM modes, as described below.

PWM mode 1
PWM output is generated from the TIOCA and TIOCC pins by pairing TGRA with TGRB and
TGRC with TGRD. The outputs specified by bits IOA3 to IOA0 and IOC3 to IOC0 in TIOR
are output from the TIOCA and TIOCC pins at compare matches A and C, respectively. The
outputs specified by bits IOB3 to IOB0 and IOD3 to IOD0 in TIOR are output at compare
matches B and D, respectively. The initial output value is the value set in TGRA or TGRC. If
the set values of paired TGRs are identical, the output value does not change when a compare
match occurs.
In PWM mode 1, a maximum 8-phase PWM output is possible.
