NAME
FUNCTION
5, 4 P43CMP1 Chip-select signals address comparison:
P43CMP0 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.
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
P42CMP0 ^{definition as P43CMP1, P43CMP0.}
P4CONA (C2H)
BIT NAME
FUNCTION
7, 6 P41FUN1 The P4.1 function control bits which are the similar definition as P43FUN1,
P41FUN0 ^P43FUN0.
5, 4 P41CMP1 The P4.1 address comparator length control bits which are the similar
P41CMP0 ^{definition as P43CMP1, P43CMP0.}
3, 2 P40FUN1 The P4.0 function control bits which are the similar definition as P43FUN1,
P40FUN0 ^P43FUN0.
1, 0 P40CMP1 The P4.0 address comparator length control bits which are the similar
P40CMP0 ^{definition as P43CMP1, P43CMP0.}
P2ECON (AEH)
BIT NAME
FUNCTION
7 P43CSINV The active polarity of P4.3 when pin P4.3 is defined as read and/or write
strobe signal.
= 1 : P4.3 is active high when pin P4.3 is defined as read and/or write strobe
signal.
= 0 : P4.3 is active low when pin P4.3 is defined as read and/or write strobe
signal.
6 P42CSINV The similarity definition as P43SINV.
5 P41CSINV The similarity definition as P43SINV.
