& Control Card Instruction Manual
4.11 Storage Flash
The 10 GB C&C Card has an optional on-chip 8-Mbyte SPI flash
memory to store user data. The flash can be erased using the FLCHIPERASE,
FLBLOCKERASE and FLBLOCKERASEW instructions. The flash can be
programmed and read in 1024-byte pages using the FLPROGRAM and
FLREAD instructions.
After performing an erase instruction (except FLBLOCKERASEW) the
user must check the busy flag in the State register (see the Variables type
ACK) to recognize the end of the erase process. While erase is being
processed no other instructions can be performed by the flash memory.
