Fig. 4.4.3.1 FOUT output waveform
Note: A hazard may occur when the FOUT signal is turned ON or OFF.
R00, R01 (when buzzer output is selected): Special output port data (0F3HD0, D1)
Controls the buzzer output.
When 1 is written: Buzzer output
When 0 is written: Low level (DC) output
Reading: Valid
BUZZER and BUZZER output can be controlled by writing data to R00 and R01.
When BUZZER output by R01 register control is selected by mask option, BUZZER output and BUZZER
output can be controlled simultaneously by writing data to R01 register.
After an initial reset, these registers are set to 0.
Figure 4.4.3.2 shows the output waveform for buzzer output.

XBZR: Buzzer frequency control (0FDHD3)
Selects the frequency of the buzzer signal.
When 1 is written: 2 kHz
When 0 is written: 4 kHz
Reading: Valid
When R00 and R01 port is set to buzzer output, the frequency of the buzzer signal can be selected by this
register.
When 1 is written to this register, the frequency is set in 2 kHz, and in 4 kHz when 0 is written.
After an initial reset, this register is set to 0.
4.4.4 Programming note
The buzzer output signal may produce hazards when the output ports R00 and R01 are turned on or off.
