• When TGR is an input capture register
(1)
Figure 12.15 shows an example of the buffer operation setting procedure.
Page 796 of 1448
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 12.14.
