This library provides routines for accessing microcontroller Flash memory. Note
that prototypes differ for PIC16 and PIC18 families.

Flash_Read(unsigned address);

// for PIC16

Flash_Read(long unsigned address);

// for PIC18

Returns data byte from Flash memory.

Reads data from the specified address in Flash memory.

Flash_Read(0x0D00);

Flash_Write(unsigned address, unsigned data);

// for PIC16

Flash_Write(unsigned long address, char *data);

// for PIC18

Writes chunk of data to Flash memory. With PIC18, data needs to be exactly 64 bytes in
size. Keep in mind that this function erases target memory before writing Data to it.
This means that if write was unsuccessful, previous data will be lost.

// Write consecutive values in 64 consecutive locations

toWrite[64];

// initialize array:

(i = 0; i < 63; i++) toWrite[i] = i;

Flash_Write(0x0D00, toWrite);
