The buzzer generator is composed of a 16-bit
PFDcounterandadutycyclecontrol.Thecoun-
ter value is set by two registers, namely BZ-H
and BZ-L. The source for this generator may be
the system clock or the X1-clock. The buzzer
generator is enabled/disabled by the register
bit
MGEN
in the configuration regis-
ter(0000H). When this bit is set high, the
buzzer generator is activated. There is another
bit in the configuration register(0000H) which
controls the buzzer output volume, bit
MDUT . If the bit is logic high, the output of
the BZ will be modulated by the X1-clock. The
clock source of the buzzer is selected by bit
BZ_CLK . When BZ_CLK=0, the clock source
is the system clock. On the other hand, when
BZ_CLK=1, the value of the selector will be the
X1-clock.
The truth table for enabling/disabling the
buzzer generator is shown in the table.
