21. APPLICATION NOTE
In-system Programming Software Examples
This application note illustrates the in-system programmability of the Winbond W79E(L)532 Flash
EPROM microcontroller. In this example, microcontroller will boot from 64 KB
APFlash
bank and
waiting for a key to enter in-system programming mode for re-programming the contents of 64 KB
APFlash. While entering in-system programming mode, microcontroller executes the loader program
in 4KB LDFlash bank. The loader program erases the 64 KB APFlash then reads the new code data
from external SRAM buffer (or through other interfaces) to update the 64KB APFlash.
If the customer uses the reboot mode to update his program, please enable this b3 or b4 of security
bits from the writer. Please refer security bits for detail descrption
EXAMPLE 1:
;*******************************************************************************************************************
;* Example of 64K APFlash program: Program will scan the P1.0. if P1.0 = 0, enters in-system
;* programming mode for updating the content of APFlash code else executes the current ROM code.
;* XTAL = 24 MHz
