Thread: USART interupts; Why use them?
face BY : Chris Fanning email (remove spam text)

I'm hoping I can ask you a quick question about FED C.

I'm looking to create a user upgradable product.  The 16F877 has
the ability to write to flash program memory which can give me this

In order to do this I want to create an assembler loader of a few
hundred bytes that can reprogram the device via serial port.   After
reprogramming (or not) I would then jump into the C program entry point.

Will your compiler allow me to reserve a specific program location for
such a piece of code?

i.e. reserve the first 200 bytes of program space that will never be
used or touched by the compiler?
