15. Buzzer Output function
The buzzer driver consists of 6-bit binary counter, the
buzzer register BUR and the clock selector. It generates
square-wave which is very wide range frequency (480
Hz~250 KHz at fxin = 4 MHz) by user programmable
counter.
Pin RB1 is assigned for output port of Buzzer driver by set-
ting the bit BUZO of RBFUNC to “1”.
The 6-bit buzzer counter is cleared and start the counting
by writing signal to the register BUR. It is increased from
00H until it matches 6-bit register BUR.
Also, it is cleared by counter overflow and count up to out-
put the square wave pulse of duty 50%.
The bit 0 to 5 of BUR determines output frequency for
buzzer driving. Frequency calculation is following as
shown below.
The bits BUCK1, BUCK0 of BUR selects the source clock
from prescaler output.
