Note1:If EXTRAM=1, all “MOVX” instructions are used for the external data memory accessing. And, if
EXTRAM=0, all “MOVX” instructions are directed to the on-chip XRAM (if address= 0x0000~0x0FFF) and USB
SFRs (if address = 0xFFC0~0xFFFF).
Note2: The cycle time for access of external data memory is:
88
7 + 2 x (ALE_Stretched_Clocks) + (RW_Stretched_Clocks)
