What is the significance of buffer registers in GPT module?? Especially usage of buffer register for "period "register??
I guess you are asking about GP timer module. The buffer registers allow these register to be updated anytime. The software can write new values to the TIMER_TMR_PER, TIMER_TMR_WID and TIMER_TMR_DLY registers. The written values are buffered and do not update into the registers until the end of the current period
