Section 11 16-Bit Timer Pulse Unit (TPU)
• When TGR is an input capture register
(1)
Figure 11.15 shows an example of the buffer operation setting procedure.
Page 760 of 1372
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 11.14.
