NAME
FUNCTION
00: Mode 0. P4.3 is a general purpose I/O port which is the same as Port1.
01: Mode 1. P4.3 is a Read Strobe signal for chip select purpose. The address
range depends on the SFR P43AH, P43AL, P43CMP1 and P43CMP0.
7, 6 ^{P43FUN1 10: Mode 2. P4.3 is a Write Strobe signal for chip select purpose. The address}
P43FUN0 range depends on the SFR P43AH, P43AL, P43CMP1 and P43CMP0.
11: Mode 3. P4.3 is a Read/Write Strobe signal for chip select purpose. The
address range depends on the SFR P43AH, P43AL, P43CMP1, and
P43CMP0.
Chip-select signals address comparison:
00: Compare the full address (16 bits length) with the base address register
P43AH, P43AL.
P43CMP1 ^{01: Compare the 15 high bits (A15 − A1) of address bus with the base address}

register P43AH, P43AL.
P43CMP0
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.
