Section 11 16-Bit Timer Pulse Unit (TPU)
11.3.2
The TMDR registers are used to set the operating mode for each channel. The TPU of the
H8S/2227 Group has a total of three TMDR registers, one each for channels 0 to 2. In other
groups, the TPU has a total of six TMDR registers, one each for channels 0 to 5. TMDR register
settings should be made only when TCNT operation is stopped.

Description
Reserved
These bits are always read as 1 and cannot be
modified.
Buffer Operation B
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.
0: TGRB operates normally
1: TGRB and TGRD used together for buffer
Buffer Operation A
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.
0: TGRA operates normally
1: TGRA and TGRC used together for buffer
Modes 3 to 0
These bits are used to set the timer operating mode.
MD3 is a reserved bit. The write value should always
be 0. See table 11.11 for details.
