Figure 9. SPI Serial Interface
The SA25F020's SPI consists of an 8-bit
instruction register that decodes a specific
instruction
to
be
different instructions (called
opcodes
) are
incorporated in the device for various
operations. Table 6 lists the instruction set
and the format for proper operation. All
opcodes, array addresses and data are
transferred
in
an
fashion. Detailed information about each of
these opcodes is provided for the individual
instruction descriptions in the sections that
follow.
