10.4.3
Buffer operation, provided for channels 0 and 3, 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 10.29 shows the register combinations used in buffer operation.

• When TGR is an output compare register
Channel
0
3
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 10.12.
