10.7.15 Reset Sync PWM Mode Buffer Operation and Compare Match Flag
When setting buffer operation for reset sync PWM mode, set the BFA and BFB bits of TMDR_4
to 0. The TIOC4C pin will be unable to produce its waveform output if the BFA bit of TMDR_4 is
set to 1.
In reset sync PWM mode, the channel 3 and channel 4 buffers operate in accordance with the BFA
and BFB bit settings of TMDR_3. For example, if the BFA bit of TMDR_3 is set to 1, TGRC_3
functions as the buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer
register for TGRA_4.
The TGFC bit and TGFD bit of TSR_3 and TSR_4 are not set when TGRC_3 and TGRD_3 are
operating as buffer registers.
Figure 10.131 shows an example of operations for TGR_3, TGR_4, TIOC3, and TIOC4, with
TMDR_3's BFA and BFB bits set to 1, and TMDR_4's BFA and BFB bits set to 0.
