Section 10 16-Bit Timer Pulse Unit (TPU)
Bit 4—Buffer Operation A (BFA): Specifies whether TGRA is to operate in the normal way, or
TGRA and TGRC are to be used together for buffer operation. When TGRC is used as a buffer
register, TGRC input capture/output compare is not generated.
In channels 1, 2, 4, and 5, which have no TGRC, bit 4 is reserved. It is always read as 0 and cannot
be modified.

Bits 3 to 0—Modes 3 to 0 (MD3 to MD0): These bits are used to set the timer operating mode.
