TRDGRD0 BFD0 = 1 Buffer register. Set the changing point of next PWM output.
TRDGRD1 BFD1 = 1 Buffer register. Set the changing point of next PWM output.
Register
Registers TRDGRC0, TRDGRC1, TRDGRD0, and TRDGRD1 are not used in PWM3 mode. To use them as
buffer registers, set bits BFC0, BFC1, BFD0, and BFD1 to 0 (general register) and write a value to the
TRDGRC0, TRDGRC1, TRDGRD0, or TRDGRD1 register. After this, bits BFC0, BFC1, BFD0, and BFD1
may be set to 1 (buffer register).
TRDGRji Register Functions in PWM3 Mode
Setting
