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.

Notes: 1. MD3 is a reserved bit. In a write, it should always be written with 0.
2. Phase counting mode cannot be set for channels 0 and 3. In this case, 0 should always
be written to MD2.
