Section 10 16-Bit Timer Pulse Unit (TPU)
Example of PWM Mode Setting Procedure: Figure 10.22 shows an example of the PWM mode
setting procedure.
Examples of PWM Mode Operation: Figure 10.23 shows an example of PWM mode 1
operation.
In this example, TGRA compare match is set as the TCNT clearing source, 0 is set for the TGRA
initial output value and output value, and 1 is set as the TGRB output value.
In this case, the value set in TGRA is used as the period, and the values set in the TGRB registers
are used as the duty levels.

Note:
Select the counter clock with bits TPSC2 to
TPSC0 in TCR. At the same time, select the
input clock edge with bits CKEG1 and CKEG0
in TCR.
Use bits CCLR2 to CCLR0
TGR to be used as the TCNT clearing source.
Use TIOR to designate the TGR as an output
compare register, and select the initial value and
output value.
Set the cycle in the TGR selected in [2], and set
the duty in the other the TGR.
Select the PWM mode with bits MD3 to MD0 in
TMDR.
Set the CST bit in TSTR to 1 start the count
operation.
