12.4.3
Buffer operation, provided for channels 0, 3, 6, and 9, 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 a compare match register.
Table 12.29 shows the register combinations used in buffer operation.

Buffer 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 12.13.
