16.2.2
RESPONSE FORMAT
The PE response set is shown in Table 16-3. All PE
responses have a general format consisting of a 32-bit
header and any required data for the response (see
16.2.2.1
Last_Cmd Field
Last_Cmd is a 16-bit field in the first word of the
response and indicates the command that the PE pro-
cessed. It can be used to verify that the PE correctly
received
the
command
that
the
programmer
transmitted.
16.2.2.2
Response Code
The
response
code
indicates
whether
the
last
command succeeded or failed, or if the command is a
value that is not recognized. The response code values
are shown in Table 16-3.
16.2.2.3
Optional Data
The response header may be followed by optional data
in case of certain commands such as read. The num-
ber of 32-bit words of optional data varies depending
on the last command operation and its parameters.
16.2.3
ROW_PROGRAM
COMMAND
The ROW_PROGRAM command instructs the PE to
program a row of data at a specified address.
The data to be programmed to memory, located in com-
mand words Data_1 through Data_N, must be
arranged using the packed instruction word format
shown in Table 16-4 (this command expects an entire
row of data).
