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.

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.

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.
time | The moment in time the power down occurs. |
