Parameters:
Prototype:
Example :
Return:
This function is copied to and executed from RAM. This function is written in
assembly code for maximum code efficiency, to minimise the RAM requirement.
This function performs programming of a single word or erasure of a single
sector of Flash. Programming a word requires approximately 50 s. Erasing a
sector requires approximately 20ms. This function is called by
ProgEepromWord and EraseEepromBank and is not callable by the application.
If EECALLBACK is defined, this function will repeatedly call the user defined
function EECallBackFunc while programming or erasure is taking place.
