◆ read()

nibble openmsx::ToshibaAudioPeriphery::read ( EmuTime::param  time)
overridevirtual

Read from (some of) the pins Some of the pins might be programmed as output, but this method doesn't care about that, it should return the value of all pins as-if they were all programmed as input.

Parameters
timeThe moment in time the read occurs

Implements openmsx::Y8950Periphery.

◆ setSPOFF()

void openmsx::ToshibaAudioPeriphery::setSPOFF ( bool  value,
EmuTime::param  time 
)
overridevirtual

SP-OFF bit (bit 3 in Y8950 register 7)

Reimplemented from openmsx::Y8950Periphery.

Definition at line 314 of file Y8950Periphery.cc.

References openmsx::Y8950::setEnabled().

◆ write()

void openmsx::ToshibaAudioPeriphery::write ( nibble  outputs,
nibble  values,
EmuTime::param  time 
)
overridevirtual

Write to (some of) the pins.

Parameters
outputsA '1' bit indicates the corresponding bit is programmed as output.
valuesThe actual value that is written, only bits for which the corresponding bit in the 'outputs' parameter is set are meaningful.
timeThe moment in time the write occurs
