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.

5, 4

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.

3, 2

P42FUN1 The P4.2 function control bits which are the similar definition as P43FUN1,

P42FUN0 P43FUN0.

1, 0

P42CMP1 The P4.2 address comparator length control bits which are the similar definition

P42CMP0 as P43CMP1, P43CMP0.
