• When TGR is an input capture register
Example of Buffer Operation Setting Procedure: Figure 10.18 shows an example of the buffer
operation setting procedure.
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 10.17.
