Register
Since values cannot be written to the TRDGRB0, TRDGRA1, or TRDGRB1 register directly after count
operation starts (prohibited item), use the TRDGRD0, TRDGRC1, or TRDGRD1 register as a buffer register.
However, to write data to the TRDGRD0, TRDGRC1, or TRDGRD1 register, set bits BFD0, BFC1, and BFD1
to 0 (general register). After this, bits BFD0, BFC1, and BFD1 may be set to 1 (buffer register).

BFD0 = 1 Buffer register. Set the changing point of next PWM1 output.
BFC1 = 1 Buffer register. Set the changing point of next PWM2 output.
BFD1 = 1 Buffer register. Set the changing point of next PWM3 output.
Setting
TRDGRji Register Functions in Complementary PWM Mode
General register. Set the PWM period at initialization.
Setting range: Setting value or above in TRD0 register
Do not write to this register when the TSTART0 and TSTART1
bits in the TRDSTR register are set to 1 (count starts).
General register. Set the changing point of PWM1 output at
initialization.
Setting range: Setting value or above in TRD0 register
Do not write to this register when the TSTART0 and TSTART1
bits in the TRDSTR register are set to 1 (count starts).
General register. Set the changing point of PWM2 output at
initialization.
Setting range: Setting value or above in TRD0 register
Do not write to this register when the TSTART0 and TSTART1
bits in the TRDSTR register are set to 1 (count starts).
General register. Set the changing point of PWM3 output at
initialization.
Setting range: Setting value or above in TRD0 register
Do not write to this register when the TSTART0 and TSTART1
bits in the TRDSTR register are set to 1 (count starts).
This register is n
(Refer to 14.3.2 Buffer Operation.)
Setting range: Setting value or above in TRD0 register
Set this register to the same value as the TRDGRB0 register
for initialization.
(Refer to 14.3.2 Buffer Operation.)
Setting range: Setting value or above in TRD0 register
Set this register to the same value as the TRDGRA1 register
for initialization.
(Refer to 14.3.2 Buffer Operation.)
Setting range: Setting value or above in TRD0 register
Set this register to the same value as the TRDGRB1 register
for initialization.
