19. Multi-Function Timer Pulse Unit 3 (MTU3c)
This bit specifies whether to operate MTU0.TGRE and MTU0.TGRF in the normal way or to use them together for
buffer operation. Compare match with TGRF occurs even when TGRF is used as a buffer register.
In MTU0 to MTU4, this bit is reserved. It is read as 0. The write value should be 0.
19.2.4
Timer Mode Register 2 (TMDR2A)
TMDR2A specifies the double buffer function in complementary PWM mode 3 (transfer at the crest and trough of the
counter value). TMDR2A value should be specified only while TCNT operation is stopped.
DRS Bit (Double Buffer Select)
This bit enables or disables the double buffer function in complementary PWM mode.
