dsPIC33F/PIC24H PROGRAMMING SPECIFICATION
4.3.1.3
QE_Code Field
TABLE 4-4:
QE_Code
0x0
0x1
0x2
No error.
Verify failed.
Other error.
The QE_Code is a byte in the first word of the
response. This byte is used to return data for query
commands and error codes for all other commands.
When the programming executive processes one of the
two query commands (QBLANK or
QVER),
the returned
opcode is always PASS and the QE_Code holds the
query response data. The format of the QE_Code for
both queries is shown in Table 4-3.
QE_Code FOR NON-QUERY
COMMANDS
Description
4.3.1.4
Response Length
TABLE 4-3:
Query
QBLANK
QVER
QE_Code FOR QUERIES
QE_Code
The response length indicates the length of the
programming executive鈥檚 response in 16-bit words.
This field includes the 2 words of the response header.
With the exception of the response for the
READP
command, the length of each response is only 2 words.
The response to the
READP
command uses the packed
instruction word format described in
Section 4.2.2
鈥淧acked Data Format鈥?
When reading an odd number
of program memory words (N odd), the response to the
READP
command is (3 * (N + 1) / 2 + 2) words. When
reading an even number of program memory words
(N even), the response to the
READP
command is (3 *
N / 2 + 2) words.
0x0F = Code memory is NOT blank
0xF0 = Code memory is blank
0xMN, where programming executive
software version = M.N
(i.e., 0x32 means software version 3.2).
When the programming executive processes any
command other than a Query, the QE_Code repre-
sents an error code. Supported error codes are shown
in Table 4-4. If a command is successfully processed,
the returned QE_Code is set to 0x0, which indicates
that there was no error in the command processing. If
the verify of the programming for the
PROGP
or
PROGC
command fails, the QE_Code is set to 0x1. For all other
programming executive errors, the QE_Code is 0x2.
