CR28 (Default 0000,0sssb)
Bit 7 : PRT_NFDD#
= 0 Enable PRT_NFDD# Function.(Default)
= 1 Disable PRT_NFDD# Function.
Bit 6 - 3: Reserved.
Bit 2 - 0: PRTMODS2 - PRTMODS0
= 0xx Parallel Port Mode
= 100 Reserved
= 101 External FDC Mode
= 110 Reserved
= 111 External two FDC Mode
When bit 7 = 0 , the bit 2 is controlled by Pin PRT_NFDD#.
