CHAPTER 4: PERIPHERAL CIARCUITS AND OPERATION (Output Ports)
R00, R01 (when buzzer output is selected): Special output port data (0F3H D0 and D1)
Controls the buzzer output.
When "1" is written: OFF
High level (DC) output (R00 can output High level only)
High level (DC) output (when "OFF level = High" is selected for R01)
Low level (DC) output (when "OFF level = Low" is selectedfot R01)
When "0" is written: ON
Buzzer output
Reading: Valid
The BUZZER and BUZZER outputs can be controlled by writing data to the R00 and R01 registers.
At initial reset, these registers are set to "1".
XBZR: Buzzer frequency control (0FDH D3)
Selects the frequency of the buzzer signal.
When "1" is written: fBZL (2 kHz when the oscillation frequency is 32 kHz)
When "0" is written: fBZH (4 kHz when the oscillation frequency is 32 kHz)
Reading: Valid
When the R01 and/or R00 ports are set as the buzzer output port, the frequency of the buzzer signal can
be selected by this register.
When "1" is written to this register, the frequency is set to fBZL (S1C6N3B0: fOSC/16, S1C6A3B0: fDVIN/16),
and fBZH (S1C6N3B0: fOSC/8, S1C6A3B0: fDVIN/8) when "0" is written.
At initial reset, this register is set to "0".
4.4.5 Programming note
The FOUT and buzzer output signals may produce hazards when the output ports R00 and R01 are
turned on or off.
