8.4.4
Buffer operation is a function of channel 0. TGRC and TGRD can be used as buffer registers.
Table 8.5 shows the register combinations for buffer operation.

The buffer operation differs, depending on whether the TGR has been set as an input capture
register or an output compare register.
When TGR Is an Output Compare Register: When a compare-match occurs, the corresponding
channel buffer register value is transferred to the general register. Figure 8.16 shows an example.
When TGR Is an Input Capture Register: When an input capture occurs, the timer counter
(TCNT) value is transferred to the general register (TGR), and the value that had been held up to
that time in the TGR is transferred to the buffer register (figure 8.17).
