Description

Timer control

register_3 (TCR_3)

H'FFFE4200

H'01

TCNT control settings

• CCLR2 to CCLR0 = B'000: Disable clearing

of TCNT.

• CKEG1 and CKEG0 = B'00: Count at rising

edge.

• TPSC2 to TPSC0 = B'001: TCNT counts

using internal clock P

φ / 4.

Timer control

register_4 (TCR_4)

H'FFFE4201

H'01

TCNT control settings

• CCLR2 to CCLR0 = B'000: Disable clearing

of TCNT.

• CKEG1 and CKEG0 = B'00: Count at rising

edge.

• TPSC2 to TPSC0 = B'001: TCNT counts

using internal clock P

φ / 4.

Timer counter_3

(TCNT_3)

H'FFFE4210

D'40

16 bit counter

In complementary PWM mode, set the initial

value to match the setting value of the timer

dead time data register (TDDR).

Timer counter_4

(TCNT_4)

H'FFFE4212

H'0000

16 bit counter

Set the initial value to H'0000.

Timer general register

A_3 (TGRA_3)

H'FFFE4218

In complementary PWM mode, set the TCNT_3

upper limit to a value of (1/2 carrier cycle + dead

time).

Timer general register

C_3 (TGRC_3)

H'FFFE4224

D'2040

In complementary PWM mode, set the initial

value of the TGRA_3 buffer register to match the

setting value of the TGRA_3 register.

Timer general register

B_3 (TGRB_3)

H'FFFE421A

In complementary PWM mode, set the PWM

output 1 compare register PWM duty (initial

output value).

Timer general register

D_3 (TGRD_3)

H'FFFE4226

D'1020

In complementary PWM mode, set the initial

value of the TGRB_3 buffer register to match the

setting value of the TGRB_3 register. New PWM

duty values are set in this register.

Timer general register

A_4 (TGRA_4)

H'FFFE421C

In complementary PWM mode, set the PWM

output 2 compare register PWM duty (initial

output value).

Timer general register

C_4 (TGRC_4)

H'FFFE4228

D'1020

In complementary PWM mode, set the initial

value of the TGRA_4 buffer register to match the

setting value of the TGRA_4 register. New PWM

duty values are set in this register.

Timer general register

B_4 (TGRB_4)

H'FFFE421E

D'1020

In complementary PWM mode, set the PWM

output 3 compare register PWM duty (initial

output value).
