opcode must be provided. Otherwise, the interface assumes that the master device
has internal logic errors and ignores the rest of the incoming signals. When nCS is
pulled back to high, the interface is back to normal. nCS should be pulled low again
for a new service request.
Table 7–10. Instruction Set for SPI
The READ and WRITE opcodes are instructions for transmission, which means the data
will be read from or written to the UFM.
WREN, WRDI, RDSR, and WRSR are instructions for the status register, where they do not
have any direct interaction with UFM, but read or set the status register within the
interface logic. The status register provides status on whether the UFM block is
available for any READ or WRITE operation, whether the interface is WRITE enabled, and
the state of the UFM WRITE protection.
the read only implementation of ALTUFM SPI (Base or Extended mode), the status
register does not exist, saving LE resources.
