NICE responds differently to good records and bad records:
o
If
the record is good, NICE sends this sequence:
ACK,LF,CR
o
If
the record is bad, NICE sends this sequence:
NAK, xx-ERR, LF, CR
xx stands for RT (Record Type error), CS (Check Sum error), or HC (invalid
Hex Code).
The Intel Hex file is composed of records. NICE processes each record as it is read!.
This means that NICE stores data in the record as it is received.
:52.
NOTE
When an error occurs, bad data may be stored in
the target system RAM. To remove the bad data
and continue dowinloading the file, issue another
Read Intel Hex File Command. Begin downloading
the file with the record that caused the error.
Because each printable ASCil character is echoed
as it is received, you may check that each char-
acter has been received properly by NICE.
