16.4.4
Buffer operation, provided for channel 0 enables TGRC and TGRD to be used as buffer registers.
Buffer operation differs depending on whether TGR has been designated as an input capture
register or as a compare match register.
Table 16.5 shows the register combinations used in buffer operation.

Buffer register
When TGR 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 illustrated in figure 16.16.
