4.0 FLASH MEMORY PROGRAMMING
The device internal flash memory can be programmed or
erased using the following two methods:
External Host Programming mode
In-Application Programming (IAP) mode
4.1 External Host Programming Mode
External host programming mode allows the user to pro-
gram the flash memory directly without using the CPU.
External host mode is entered by forcing PSEN# from a
logic high to a logic low while RST input is being held con-
tinuously high. The device will stay in external host mode
as long as RST = 1 and PSEN# = 0.
A Read-ID operation is necessary to “arm” the device in
external host mode, and no other external host mode com-
mands can be enabled until a Read-ID is performed. In
external host mode, the internal flash memory blocks are
accessed through the re-assigned I/O port pins (see Figure
4-1 for details) by an external host, such as a MCU program-
mer, a PCB tester or a PC-controlled development board.

signifies a negative pulse and the command is asserted during the low state of PROG#/ALE input.
All other combinations of the above input pins are invalid and may result in unexpected behaviors.
