11.4.3
Buffer operation, provided for channels 0, 3, and 4, enables TGRC and TGRD to be used as buffer
registers. In channel 0, TGRF can also be used as a buffer register.
Buffer operation differs depending on whether TGR has been designated as an input capture
register or as a compare match register.
Note: TGRE_0 cannot be designated as an input capture register and can only operate as a
Table 11.43 shows the register combinations used in buffer operation.

When a compare match occurs, the value in the buffer register for the corresponding channel is
transferred to the timer general register.
