XBZOUT: R00 output selection register (FF65HD0)
Selects the R00 terminal function.
When "1" is written: XBZ output
When "0" is written: General-purpose DC output
Reading: Valid
When using the R00 terminal for the XBZ output, write "1" to this register. Furthermore, fix the R00
register at "1" and the R00HIZ register at "0".
At initial reset, this register is set to "0".
BZOUT: R01 output selection register (FF65HD1)
Selects the R01 terminal function.
When "1" is written: BZ output
When "0" is written: General-purpose DC output
Reading: Valid
When using the R01 terminal for the BZ output, write "1" to this register. Furthermore, fix the R01 register
at "1" and the R01HIZ register at "0".
At initial reset, this register is set to "0".
BZE: BZ output control register (FF6CHD0)
Controls the buzzer signal output.
When "1" is written: Buzzer output ON
When "0" is written: Buzzer output OFF
Reading: Valid
When "1" is written to BZE, the BZ signal is output from the BZ (R01) terminal and the XBZ signal is
output from the XBZ (R00) terminal.
When "0" is written, the buzzer signals go OFF.
At initial reset, this register is set to "0".
BZFQ0–BZFQ2: Buzzer frequency selection register (FF6EHD0–D2)
Selects the buzzer signal frequency.
