void reset(EmuTime::param time) override
This method is called on reset.

~SunriseIDE() override
SunriseIDE(const DeviceConfig &config)
Definition: SunriseIDE.cc:10
void writeMem(word address, byte value, EmuTime::param time) override
Write a given byte to a given location at a certain time to this device.
Definition: SunriseIDE.cc:77
void serialize(Archive &ar, unsigned version)

const byte * getReadCacheLine(word start) const override
Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.
Definition: SunriseIDE.cc:63
void powerUp(EmuTime::param time) override
This method is called when MSX is powered up.
Definition: SunriseIDE.cc:27
