the TCNT4 count clock, this setting is invalid and input capture does not
occur.
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 does not
occur.
Note: When TGRC or TGRD is designated for buffer operation, this setting is invalid and the
register operates as a buffer register.
