* DESCRIPTION:
*       Simulate QuaterDeck Device(88E6052)'s register map. When QuareterDeck API
*        try to read/write a bit or bits into QuaterDeck, the simulator will redirect to
*         its own memory place and performing the function very close to QuaterDeck.
*        For example,
*        1) user can set/reset a certain bit of QuarterDeck registers(Phy,Port,and General registers).
*        2) user can access ATU (flush, load, purge, etc. with max MAC addresses of 32)
*        3) user can manually generate an Interrupt and test the Interrupt routine.
*        4) when user read a register, it will clear a certain register if it's a Self Clear register.
*        5) when user write a register, it will return ERROR if it's read only register.
*
*
* DEPENDENCIES:   QuaterDeck (88E6052) Register MAP.
