11.9 Buzzer Driver

11.9.1 Overview

The Buzzer consists of 8bit counter, buzzer data register (BUZDR) and buzzer control register (BUZCR). The Square

Wave (61.035Hz~125.0kHz @ 8MHz)is outputted through P13/SEG17/AN10/EC1/BUZO pin. The buzzer data

BUCK[1:0] selects source clock divided by prescaler.
