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

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.
1 When bits TPSC2 to TPSC0 in TCR4 are set to B'000 and /1 is used as
the TCNT4 count clock, this setting is invalid and input capture is not
generated.
