byte * getWriteCacheLine(word address) const override
Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for writing.
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.
const byte * getReadCacheLine(word address) const override
Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.
byte readIO(word port, EmuTime::param time) override
Read a byte from an IO port at a certain time from this device.
