Note: *1 When the BFA bit in TMDR3 is set to 1 and TGR3C is used as a buffer register,
this setting is invalid and input capture/output compare is not generated.

*: Don't care
Notes: *1 When bits TPSC2 to TPSC0 in TCR4 are set to B'000 and ø/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.
Note: When TGRC or TGRD is designated for buffer operation, this setting is invalid and the
register operates as a buffer register.
