The example demonstrates simple write to the flash memory for AVR, then reads the data and dis-
plays it on PORTB and PORTD.

program Flash_MCU_test;

const F_ADDRESS : longint = 0x200;

const data_ : array[32] of word = (                          // constant table

0x0000,0x0001,0x0002,0x0003,0x0004,0x0005,0x0006,0x0007,
