• Bit 3 (PWM Mode 3 (PWM3)): PWM3 selects the PWM mode for channel 3. When the
PWM3 bit is set to 1 and PWM mode is entered, the TIOCA3 pin becomes a PWM output pin.
1 is output on a compare match of general register A3 (GRA3); 0 is output on a compare match
of general register B3 (GRB3). When complementary PWM mode or reset-synchronized PWM
mode is set by the CMD1 and CMD0 bits in the timer function control register (TFCR), the
setting of this bit is ignored in favor of the settings of CMD1 and CMD0.
Bit 3: PWM3 Description
0 Channel 3 operates normally (Initial value)
1 Channel 3 operates in PWM mode
• Bit 2 (PWM Mode 2 (PWM2)): PWM2 selects the PWM mode for channel 2. When the
PWM2 bit is set to 1 and PWM mode is entered, the TIOCA2 pin becomes a PWM output pin.
1 is output on a compare match of general register A2 (GRA2); 0 is output on a compare match
of general register B2 (GRB2).
Bit 2: PWM2 Description
0 Channel 2 operates normally (Initial value)
1 Channel 2 operates in PWM mode
• Bit 1 (PWM Mode 1 (PWM1)): PWM1 selects the PWM mode for channel 1. When the
PWM1 bit is set to 1 and PWM mode is entered, the TIOCA1 pin becomes a PWM output pin.
1 is output on a compare match of general register A1 (GRA1); 0 is output on a compare match
of general register B1 (GRB1).
Bit 1: PWM1 Description
0 Channel 1 operates normally (Initial value)
1 Channel 1 operates in PWM mode
• Bit 0 (PWM Mode 0 (PWM0)): PWM0 selects the PWM mode for channel 0. When the
PWM0 bit is set to 1 and PWM mode is entered, the TIOCA0 pin becomes a PWM output pin.
1 is output on a compare match of general register A0 (GRA0); 0 is output on a compare match
of general register B0 (GRB0).
Bit 0: PWM0 Description
0 Channel 0 operates normally (Initial value)
1 Channel 0 operates in PWM mode
