The other is the direct access through GPIO register table that can be configured by {CR61, CR60} of
logic device 8. The mapped 5 registers are defined in table 11.2. Since the base address is set, the
GPIO number can be selected by writing the group number to GSR [INDEX] (GPIO Select Register,
#1~#6 for GPIO1 ~ GPIO6 respectively; #0 and #7 is invalid for GSR [INDEX]). Then the I/O register,
the Data register and the Inversion register are mapped to addresses Base+0, Base+1 and Base+2
respectively. Only one GPIO can be accessed at one time.
