Note: Bits 7 to 2 are reserved in channel 5. These bits are always read as 0. The write value
should always be 0.
11.3.2 Timer Mode Register (TMDR)
The TMDR registers are 8-bit readable/writable registers that are used to set the operating mode of
each channel. The MTU2 has five TMDR registers, one each for channels 0 to 4. TMDR register
settings should be changed only when TCNT operation is stopped.

R/W Buffer Operation E
Specifies whether TGRE_0 and TGRF_0 are to operate
in the normal way or to be used together for buffer
operation. Compare match with TGRF occurs even
when TGRF is used as a buffer register.
In channels 1 to 4, this bit is reserved. It is always read
as 0 and the write value should always be 0.
0: TGRE_0 and TGRF_0 operate normally
1: TGRE_0 and TGRF_0 used together for buffer
operation
