Field Programming of FLASH PICmicros
With the ICSP interface circuitry already in place, FLASH-based PICmicros can be easily repro-
grammed in the field. These FLASH devices allow you to reprogram them even if they are code
protected. A portable ICSP programming station might consist of a laptop computer and pro-
grammer. The technician plugs the ICSP interface cable into the application circuit and down-
loads the new firmware into the PICmicro. The next thing you know the system is up and running
without those annoying “bugs.” Another instance would be that you want to add an additional fea-
ture to your system. All of your current inventory can be converted to the new firmware and field
upgrades can be performed to bring your installed base of systems up to the latest revision of
firmware.
