range depends on the SFR P41AH,P41AL,P41CMP1 and P41CMP0.
11: Mode 3. P4.1 is a Read/Write Strobe signal for chip select purpose. The
address range depends on the SFR P41AH, P41AL, P41CMP1, and P41CMP0.
Chip-select signals address comparison:
00: Compare the full address (16 bits length) with the base address register
P41AH, P41AL.
01: Compare the 15 high bits (A15-A1) of address bus with the base address
register P41AH, P41AL.
10: Compare the 14 high bits (A15-A2) of address bus with the base address
register P41AH, P41AL.
11: Compare the 8 high bits (A15-A8) of address bus with the base address
register P41AH, P41AL.
The P4.0 function control bits which are the similar definition as P40FUN1,
P40FUN0. .
The P4.0 address comparator length control bits which are the similar definition
as P40CMP, P40CMP0.
FUNCTION
The P4.3 function control bits which are the similar definition as P43FUN1, P43FUN0. .
The P4.3 address comparator length control bits which are the similar definition as
P43CMP1,P43CMP0.
The P4.2 function control bits which are the similar definition as P42FUN1, P42FUN0. .
The P4.2 address comparator length control bits which are the similar definition as
P42CMP1,P42CMP0.
FUNCTION
The programming address of on-chip flash memory in programming mode.
SFRFAL contains the low-order byte of address.
