TRG3C I/O Control

Output disabled

0 output at compare match

1 output at compare match

Toggle output at compare match

Notes:

Note: When the BFA bit in TMDR3 is set to 1 and TGR3C is used as a buffer

generated.

Note: When TGRC or TGRD is designated for buffer operation, this setting is invalid and the register operates as a buffer register.

1. When bits TPSC2 to TPSC0 in TCR4 are set to B'000 and

φ/1 is used as the TCNT4 count clock,

this setting is invalid and input capture is not generated.

2. When the BFB bit in TMDR3 is set to 1 and TGR3D is used as a buffer register, this setting is invalid

and input capture/output compare is not generated.
