[1]

Clear bits STR0 and STR1 in TSTR to 0, and

stop the counter operation of TCNT_0. Stop

TCNT_0 and TCNT_1 and set complementary

PWM mode.

[2]

Write H'00 to TOCR.

[3]

Use bits TPSC2 to TPSC0 in TCR to select the

same counter clock for channels 0 and 1. When

an external clock is selected, select the edge of

the external clock by bits CKEG1 and CKEG0 in

TCR. Do not use bits CCLR1 and CCLR0 in

TCR to clear the counter.

[4]

Use bits CMD1 and CMD0 in TFCR to set

complementary PWM mode. FTIOB0 to FTIOD0

and FTIOA1 to FTIOD1 automatically become

PWM output pins.

[5]

Set H'00 to TOCR.

[6]

TCNT_1 must be H'0000. Set a non-overlapped

period to TCNT_0.

[7]

GRA_0 is a cycle register. Set the cycle to

GRA_0. Set the timing to change the PWM

output waveform to GRB_0, GRA_1, and

GRB_1. Note that the timing must be set within

the range of compare match carried out for

TCNT_0 and TCNT_1.

For GR settings, see 3. Setting GR Value in

Complementary PWM Mode in section 14.4.7,

Complementary PWM Mode.

[8]

Use TOER to enable or disable the timer output.

[9]

Set the STR0 and STR1 bits in TSTR to 1 to

start the count operation.

[1]

Complementary PWM mode

Stop counter operation

Note:

To re-enter complementary PWM mode, first, enter a mode other than the complementary

PWM mode. After that, repeat the setting procedures from step [1].

For settings of waveform outputs with a duty cycle of 0% and 100%, see the settings shown

in 2. Examples of Complementary PWM Mode Operation and 3. Setting GR Value in

Complementary PWM Mode in section 14.4.7, Complementary PWM Mode.

[2]

PWM mode

[5]

Initialize output pin

[6]

Set TCNT

[7]

Set GR

[8]

Enable waveform output

[9]

Start counter operation
