The AT89C51CC03 flash memory is divided in several blocks:
Block 0: from address 0000h to 1FFFh
Block 1: from address 2000h to 3FFFh
Block 2: from address 4000h to 7FFFh
These three blocks contain 128 pages.

Note:
This routine allows to start at the beginning of the bootloader as after a reset. After calling this
routine the regular boot process is performed and the communication must be opened before
any action.
