Bit 3 (PWM Mode 3 (PWM3)): PWM3 selects the PWM mode for channel 3. When the

PWM3 bit is set to 1 and the PWM mode 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 the complementary PWM mode or reset-

synchronized PWM mode are set by the CMD1 and CMD0 bits of the timer function control

Bit 3: PWM3

Description

Channel 3 operates normally (initial value)

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 the PWM mode 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

Channel 2 operates normally (initial value)

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 the PWM mode 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

Channel 1 operates normally (initial value)

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 the PWM mode 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

Channel 0 operates normally (initial value)

Channel 0 operates in PWM mode
