This operation is illustrated in figure 10.12.
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 10.13.

Designate TGR as an input capture register or
output compare register by means of TIOR.
Designate TGR for buffer operation with the
BFA and BFB bits in TMDR.
Set the CST bit in TSTR to 1 start the count
operation.
