5.1.3
The programming executive does not use the Watch-
dog Timer or time-out for transmitting responses to the
programmer. If the programmer does not follow the flow
control mechanism using PGCx, as described in
Section 5.1.1 “Communication Interface and Proto-
col”, it is possible that the programming executive will
behave unexpectedly while trying to send a response
to the programmer. Since the programming executive
does not have a time-out, it is imperative that the pro-
grammer correctly follow the described communication
protocol.
FIGURE 5-3:
5.2
The programming executive command set is listed in
Table 5-1. This table contains the opcode, mnemonic,
length, time-out and description for each command.
Section 5.2.4 “Command Descriptions” provides
functional details on each command.
5.2.1
The programming executive commands have a
general format consisting of a 16-bit header and any
required data for the command (see Figure 5-4). The
16-bit header consists of a 4-bit opcode field, which is
used to identify the command, followed by a 12-bit
command length field.

As a safety measure, the programmer should use the
command time-outs identified and listed in Table 5-1. If
the command time-out expires, the programmer should
reset
programming the device again.
The command opcode must match one of those in the
command set. Any command that is received that does
not match the list in Table 5-1 returns a “NACK”
response (see Section 5.3.1.1 “Opcode Field”).
The command length is represented in 16-bit words as
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.
