Bit 3—PWM Mode 3 (PWM3): Selects whether channel 3 operates normally or in PWM mode.

Bit 3

PWM3

Description

Channel 3 operates normally

(Initial value)

Channel 3 operates in PWM mode

When bit PWM3 is set to 1 to select PWM mode, pin TIOCA3 becomes a PWM output pin. The

output goes to 1 at compare match with general register A3 (GRA3), and to 0 at compare match

with general register B3 (GRB3).

If complementary PWM mode or reset-synchronized PWM mode is selected by bits CMD1 and

CMD0 in the timer function control register (TFCR), the CMD1 and CMD0 setting takes

precedence and the PWM3 setting is ignored.

Bit 2—PWM Mode 2 (PWM2): Selects whether channel 2 operates normally or in PWM mode.

Bit 2

PWM2

Description

Channel 2 operates normally

(Initial value)

Channel 2 operates in PWM mode

When bit PWM2 is set to 1 to select PWM mode, pin TIOCA2 becomes a PWM output pin. The

output goes to 1 at compare match with general register A2 (GRA2), and to 0 at compare match

with general register B2 (GRB2).

Bit 1—PWM Mode 1 (PWM1): Selects whether channel 1 operates normally or in PWM mode.

Bit 1

PWM1

Description

Channel 1 operates normally

(Initial value)

Channel 1 operates in PWM mode

When bit PWM1 is set to 1 to select PWM mode, pin TIOCA1 becomes a PWM output pin. The

output goes to 1 at compare match with general register A1 (GRA1), and to 0 at compare match

with general register B1 (GRB1).
