• When TGR is an input capture register

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 12.15.

[1] Designate TGR as an input capture register or

output compare register by means of TIOR.

[2] Designate TGR for buffer operation with bits

BFA and BFB in TMDR.

[3] Set the CST bit in TSTR to 1 start the count

operation.
