Hello all,
Those who usually program microcontrollers in assembly, should be well familiar with the internal EEPROM (Series PIC18F).
In particular there's a register EECON2, that needs to be initialized ALWAYS with 0x55 then 0xAA before writing;
Why is that? What's the main reason behind these proper values?
Thanks.
