const byte * getReadCacheLine(word address) const override
Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.
byte * getWriteCacheLine(word address) const override
Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for writing.
void reset(EmuTime::param time) override
This method is called on reset.
byte peekMem(word address, EmuTime::param time) const override
Read a byte from a given memory location.
byte readMem(word address, EmuTime::param time) override
Read a byte from a location at a certain time from this device.
NowindInterface(const DeviceConfig &config)
void serialize(Archive &ar, unsigned version)
void writeMem(word address, byte value, EmuTime::param time) override
