Access in Reading
To read the user data area, the user has to specify the address of the first byte to be read, and the total
number of bytes to be read.
Remark :
Even if the size of the memory area is of 32 bytes, the address of the first element to be read is
coded on two bytes ; because this area is more important on other equipments.
