Goal: To write and read EEPROM

What we have: PIC16f628a and a simple devboard.

Microcontroller PIC16f628a has 128 bytes of EEPROM memory on board, not too much but we have what we have. Hi-tech PICC compiler has internal functions for work with EEPROM, but here I’m going to make some my personal functions.

Let’s look at the EECON1 register:
