10.5.3
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 10.17 shows the register combinations used in buffer operation.

• When TGR is an input capture register
Channel
0
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 10.17.
When input capture occurs, the value in TCNT is transferred to TGR and the value previously
held in the timer general register is transferred to the buffer register.
This operation is illustrated in figure 10.18.
