Buffer Operation
Buffer operation, provided for TPU0 and TPU3 (TPU6 and TPU9), enables TPUm.TGRC and TPUm.TGRD to be used
as buffer registers.
Buffer operation differs depending on whether TPUm.TGRy has been set as an input capture register or a compare match
register.
Table 15.23 lists the register combinations used in buffer operation.

When TPUm.TGRy is an output compare register
When a compare match occurs, the value in the buffer register for the corresponding channel is transferred to the
timer general register.
This operation is shown in figure 15.13.
