Section 11 Multi-Function Timer Pulse Unit 2 (MTU2)
(3)
The timing for transfer from buffer registers to timer general registers can be selected in PWM
mode 1 or 2 for channel 0 or in PWM mode 1 for channels 3 and 4 by setting the buffer operation
transfer mode registers (TBTM_0, TBTM_3, and TBTM_4). Either compare match (initial
setting) or TCNT clearing can be selected for the transfer timing. TCNT clearing as transfer
timing is one of the following cases.
• When TCNT overflows (H'FFFF to H'0000)
• When H'0000 is written to TCNT during counting
• When TCNT is cleared to H'0000 under the condition specified in the CCLR2 to CCLR0 bits
Note: TBTM must be modified only while TCNT stops.
Figure 11.19 shows an operation example in which PWM mode 1 is designated for channel 0 and
buffer operation is designated for TGRA_0 and TGRC_0. The settings used in this example are
TCNT_0 clearing by compare match B, 1 output at compare match A, and 0 output at compare
match B. The TTSA bit in TBTM_0 is set to 1.
