This class implements the MSX Turbo-R pause key.
Whenever the pause key is pressed a flip-flop is toggled. The status of this flip-flop can be read from io-port 0xA7. bit 0 indicates the status (1 = pause active) all other bits read 0

Read a byte from a given IO port.
Reading via this method has no side effects (doesn't change the device status). If safe 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 just returns 0xFF.

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.
