11.9 Buzzer Driver
11.9.1 Overview
The Buzzer consists of 8 bit counter, buzzer data register (BUZDR), and buzzer control register (BUZCR). The
Square Wave (61.035Hz~125.0 kHz @8MHz) is outputted through P13/SEG17/AN10/EC1/BUZO pin. The
buzzer data register (BUZDR) controls the buzzer frequency (look at the following expression). In buzzer control
register (BUZCR), BUCK[1:0] selects source clock divided by prescaler.
