◆ peekIO()

byte openmsx::VDPIODelay::peekIO ( word  port,
EmuTime::param  time 
) const
overridevirtual

Read a byte from a given IO port.

Reading via this method has no side effects (doesn't change the device status). If safe reading is not possible this method returns 0xFF. This method is not used by the emulation. It can however be used by a debugger. The default implementation just returns 0xFF.

◆ readIO()

byte openmsx::VDPIODelay::readIO ( word  port,
EmuTime::param  time 
)
overridevirtual

Read a byte from an IO port at a certain time from this device.

The default implementation returns 255.

◆ writeIO()

void openmsx::VDPIODelay::writeIO ( word  port,
byte  value,

overridevirtual

Write a byte to a given IO port at a certain time to this device.

The default implementation ignores the write (does nothing)
