11.3.6 Timer Buffer Operation Transfer Mode Register (TBTM)
The TBTM registers are 8-bit readable/writable registers that specify the timing for transferring
data from the buffer register to the timer general register in PWM mode. This module has three
TBTM registers, one each for channels 0, 3, and 4.

Value R/W Description
7 to 3 All 0 R Reserved
These bits are always read as 0. The write value should
always be 0.
2 TTSE 0 R/W Timing Select E
Specifies the timing for transferring data from TGRF_0
to TGRE_0 when they are used together for buffer
operation.
In channels 3 and 4, bit 2 is reserved. It is always read
as 0 and the write value should always be 0.
0: When compare match E occurs in channel 0
1: When TCNT_0 is cleared
1 TTSB 0 R/W Timing Select B
Specifies the timing for transferring data from TGRD to
TGRB in each channel when they are used together for
buffer operation.
0: When compare match B occurs in each channel
1: When TCNT is cleared in each channel
0 TTSA 0 R/W Timing Select A
Specifies the timing for transferring data from TGRC to
TGRA in each channel when they are used together for
buffer operation.
0: When compare match A occurs in each channel
1: When TCNT is cleared in each channel
