Sample Buffering Setup Procedure
Figure 10.48 shows a sample buffering setup procedure.
Examples of Buffering
Figure 10.49 shows an example in which GRA is set to function as an output compare register
buffered by BRA, TCNT is set to operate as a periodic counter cleared by GRB compare match,
and TIOCA and TIOCB are set to toggle at compare match A and B. Because of the buffer setting,
when TIOCA toggles at compare match A, the BRA value is simultaneously transferred to GRA.
This operation is repeated each time compare match A occurs. Figure 10.50 shows the transfer
timing.

Set TIOR to select the output compare or input
capture function of the general registers.
Set bits BFA3, BFA4, BFB3, and BFB4 in TFCR
to select buffering of the required general registers.
Set the STR bits to 1 in TSTR to start the timer
counters.
