Note:
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
Block 3: from address 8000h to BFFFh
Block 4: from address C000h to FFFFh
These five blocks contain 256 pages.
Instruction: LCALL FFC0h.
At the complete API execution by the bootloader, the value to read is in the api_value
variable.
