Description
D25 and CCUME application (FLASH) code).
Note:
The Monitor accepts S1, S2 and S3 data records, and S7, S8 and S9 end records, and
optional S0 comment records in the downloaded file. The monitor rejects all other
types of records.
Once the command verifies the checksum within the record, the contents of data
records (S1, S2 or S3) are stored in memory. When it receives an S7, S8 or S9 end
record, the DOWNLOAD command returns control to the Monitor's command line.

Results: This prepares the monitor to receive Motorola S-
records over the serial port. The monitor does not
echo any further until it encounters an end record
(the prompt returns at this point) or a format or
record checksum error (this returns an error
message before returning the prompt).
Each S-record, terminated by a carriage return or line feed,
cannot exceed 80 decimal bytes in length.
Application code download works ONLY when:
•
The BootROM code is being executed AND
•
The FLASH region has been erased.
