Prognbyte
Prognbyte is a long command supporting the address field. With this command it is possible to
program only a portion of the selected block. The block and the page information are transmitted
in the address field.
The program code is 63h, and includes the 2-bit command CRC
If the page is locked, only the upper byte (admin byte) of the upper block is changeable. Then
this byte works the same as an OTP memory.
