Descriptions”).
4.2.1
All programming executive commands have a general
format consisting of a 16-bit header and any required
data for the command (see
header consists of a 4-bit opcode field, which is used to
identify the command, followed by a 12-bit command
length field.
FIGURE 4-3:
The command opcode must match one of those in the
command set. Any command that is received which
does not match the list in
response (see
The command length is represented in 16-bit words
since the SPI operates in 16-bit mode. The
programming executive uses the command length field
to determine the number of words to read from the SPI
port. If the value of this field is incorrect, the command
will not be properly received by the programming
executive.

4.2.2
When 24-bit instruction words are transferred across
the 16-bit SPI interface, they are packed to conserve
space using the format illustrated in
format minimizes traffic over the SPI and provides the
programming executive with data that is properly
aligned for performing table write operations.

The
unsupported commands. Additionally, due to the
memory constraints of the programming executive, no
checking is performed on the data contained in the
programmer command. It is the responsibility of the
programmer to command the programming executive
with valid command arguments or the programming
operation may fail. Additional information on error
handling is provided in
