16.2.5
The PROGRAM command instructs the PE to program
Flash memory, including Configuration Words, starting
from the 32-bit address specified in the Addr_Low and
Addr_High fields. The address must be aligned to a
512-byte boundary (aligned to Flash row size). Also,
the length must be a multiple of 512 bytes (multiple of
the Flash row size).
FIGURE 16-7:
TABLE 16-6:
There are three programming scenarios:
1.
2.
3.
When the data length is equal to 512 bytes, the PE
receives the 512-byte block of data from the probe and
immediately sends the response for this command
back to the probe.

When the data length is equal to 1024 bytes, the PE
receives the first two 512-byte blocks of data from the
probe sequentially. The PE sends the response with
the status of the write operation for the first 512-byte
block back to the probe, followed immediately by the
status of the write operation for the second 512-byte
block.
If the data to be programmed is larger than 1024 bytes,
the PE receives the first two 512-byte blocks of data
from the probe sequentially. The PE sends the
response for the first 512-byte block of data back to the
probe. The PE receives the third 512-byte block probe
and sends the response for the second 512-bye block
back to the probe. Successive blocks from the probe
and subsequent responses to the probe are received
and sent same way. After receiving the last 512-byte
block from the probe, the PE sends the response for
the second-to-last block to the probe, followed by the
response for the last block.
If the PE encounters an error in programming any of
the blocks, it sends a failure status to the probe. On
receiving the failure status, the probe must stop send-
ing data. The PE does not receive any other data for
this command from the probe. The process is
illustrated in Figure 16-9.
The response for this command is a little different than
the response for other commands. The 16 MSbs of the
response contain the 16 LSbs of the destination
address, where the last block is programmed. This
helps the probe and the PE maintain proper
synchronization of sending, and receiving, data and
responses.
Expected Response (1 word):

Note:
If the PROGRAM command fails, the
programmer should read the failing row
using the READ command from the Flash
memory. Next, the programmer should
compare the row received from Flash
memory to its local copy, word-by-word, to
determine the address where Flash
programming fails.
