For More Information On This Product,
;because MBAR is an internal register, MBARx is used as
;label for the memory map address
;set up the PAR. PP[7:0] set up as I/O
;set PP[7:4] as outputs; PP[3:0] as inputs
;0xA0 written into PADAT; PP[7:4] being outputs,
;PP[7:4] becomes 1010; i.e. PP7, PP5 = 1 and
;PP6, PP4 = 0
