FUNCTION
Chip-select signals address comparison:
00: Compare the full address (16 bits length) with the base address register
P43AH, P43AL.
01: Compare the 15 high bits (A15
A1) of address bus with the base address
register P43AH, P43AL.
10: Compare the 14 high bits (A15
A2) of address bus with the base address
register P43AH, P43AL.
11: Compare the 8 high bits (A15
A8) of address bus with the base address
register P43AH, P43AL.
