9.2.2
The TMDR registers are 8-bit readable/writable registers that are used to set the operating mode
for each channel. The TPU has six TMDR registers, one for each channel. The TMDR registers
are initialized to H'C0 by a reset, and in hardware standby mode.
Note: Make TMDR settings only when TCNT operation is stopped.
Bits 7 and 6—Reserved: Read-only bits, always read as 1.
Bit 5—Buffer Operation B (BFB): Specifies whether TGRB is to operate in the normal way, or
TGRB and TGRD are to be used together for buffer operation. When TGRD is used as a buffer
register, TGRD input capture/output compare is not generated.
In channels 1, 2, 4, and 5, which have no TGRD, bit 5 is reserved. It is always read as 0 and
cannot be modified.
