Member Function Documentation

◆ getExtraDeviceInfo()

void openmsx::MSXFDC::getExtraDeviceInfo ( TclObject result) const
overridevirtual
See also
getDeviceInfo() Default implementation does nothing. Subclasses can override this method to add extra info (like subtypes).

Reimplemented from openmsx::MSXDevice.

References rom.

◆ getReadCacheLine()

const byte * openmsx::MSXFDC::getReadCacheLine ( word  start) const
overridevirtual

Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.

If it is, a pointer to a buffer containing this interval must be returned. If not, a null pointer must be returned. Cacheable for reading means the data may be read directly from the buffer, thus bypassing the readMem() method, and thus also ignoring EmuTime. The default implementation always returns a null pointer. The start of the interval is CacheLine::SIZE aligned.

Reimplemented from openmsx::MSXDevice.

Reimplemented in openmsx::NationalFDC, openmsx::PhilipsFDC, openmsx::SanyoFDC, openmsx::SpectravideoFDC, openmsx::TalentTDC600, openmsx::ToshibaFDC, openmsx::TurboRFDC, openmsx::VictorFDC, and openmsx::YamahaFDC.

◆ peekMem()

byte openmsx::MSXFDC::peekMem ( word  address,
EmuTime::param  time 
) const
overridevirtual

Read a byte from a given memory location.

Reading memory via this method has no side effects (doesn't change the device status). If save 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 uses the cache mechanism (getReadCacheLine() method). If a certain region is not cacheable you cannot read it by default, Override this method if you want to improve this behaviour.

◆ powerDown()

void openmsx::MSXFDC::powerDown ( EmuTime::param  time)
overridevirtual

This method is called when MSX is powered down.

The default implementation does nothing, this is usually ok. Typically devices that need to turn off LEDs need to reimplement this method.

Parameters
timeThe moment in time the power down occurs.

◆ readMem()

byte openmsx::MSXFDC::readMem ( word  address,
EmuTime::param  time 
)
overridevirtual

Read a byte from a location at a certain time from this device.

The default implementation returns 255.
