B. When buffer operation is used and TPSC2 = TPSC1 = TPSC0 = 0.

To change duty cycles while a waveform with a duty cycle of 0% and 100% is being output,
the following procedure must be followed.
Write H'0000 or a value equal to or more than the GRA_0 value to the buffer register.
Write a value which satisfies GRA_0 + 1 < GR < H'FFFF to GR directly at the timing
shown below.
Write a value which satisfies GRA_0 + 1 < GR < H'FFFF to the buffer register. A
waveform with a duty cycle of 0% can be output. However, a waveform with a duty cycle
of 100% cannot be output using the buffer operation. Also, the buffer operation cannot be
used to change duty cycles while a waveform with a duty cycle of 100% is being output.
For details on buffer operation, see section 12.4.8, Buffer Operation.
To output a 100%-duty cycle waveform, write H'0000 while previous GR value <
TCNT_0 GRA_0.
To change duty cycles while a waveform with a duty cycle of 0% or 100% is being
output, make sure the following procedure.
To change duty cycles while a 0%-duty cycle waveform is being output, write to GR
while H'0000 TCNT_1 < previous GR value.
To change duty cycles while a 100%-duty cycle waveform is being output, write to GR
while previous GR value< TCNT_0 GRA_0.
Note that changing from a 0%-duty cycle waveform to a 100%-duty cycle waveform
To output a 0%-duty cycle waveform, write a value equal to or more than the
GRA_0value to the buffer register.
To output a 100%-duty cycle waveform, write H'0000 to the buffer register.
For details on buffer operation, see section 12.4.8, Buffer Operation.
To output a 0%-duty cycle waveform, write the value while H'0000 is TCNT_1 <
previous GR value
To output a 100%-duty cycle waveform, write the value while previous GR value <
TCNT_0 GRA_0.
To change duty cycles while a 0%-duty cycle waveform is being output, write to GR
while H'0000 TCNT_1 < previous GR value.
To change duty cycles while a 100%-duty cycle waveform is being output, write to GR
while previous GR value< TCNT_0 GRA_0.
Note that changing from a 0%-duty cycle waveform to a 100%-duty cycle waveform
and vice versa is not possible.
