The IMFA bit of channel 3 is set to 1 for increment pulses and the OVF bit of channel 4 is set to 1
for underflows only. The buffer register (BR) set for the buffer operation is transferred to the GR
upon compare match A3 (when incrementing) or TCNT4 underflow.
GR Setting in Complementary Mode: Be aware of the following when setting the general
registers in complementary PWM mode and when making changes during operation.
• Initial values: Setting H'0000 to T–1 (the initial setting T: TCNT3) is prohibited. After
• Methods of changing settings: Use the buffer operation. Writing directly to general registers
• When changing settings: See figure 10.38.
