Hey William, Thanks for the link. That was really helpful. According to it, they have only 4K memory reserved for Flash in the EEPROM which is equal to 1K words. So, going by your suggestion, if I go at writing flash directly for 8K of data, then I wont have at readily available on power-on right? As far as I understand, the library doesnt support more than 4K of flash, but then it shouldnt mean, that 1K is the max memory that can be used as non-volatile memory , right? I mean, I should be able to write to 8K of non-volatile memory, since this link here - http://www.embeddeddesignindia.co.in/ART_8800571198_2800001_TA_102100b4.HTM says that PIC 8/16-bit has upto 128K of non-volatile memory. AM I correct i= n understanding that 4K limitation of EEPROM is a limitation of the library and not of the PIC32MX family, right?
