OPERATION
68EVB912B32UM/D 3-33
LOAD Load S-Record File LOAD
syntax:
LOAD [<AddressOffset>]
{ Send File}
where:
<AddressOffset> is an optional 16-bit hexadecimal number.
{Send File} is the host-computer communications program’s utility for sending
an ASCII (text) file. Refer to Appendix B

Communications
Program Examples.
The LOAD command is used to load S-Record object files into memory from an external device.
The address offset, if supplied, is added to the load address of each S-Record before its data bytes
are placed in memory. Providing an address offset other than zero allows object code or data to
be loaded into memory at a location other than that for which it was assembled. During the
loading process, the S-Record data is not echoed to the control console. However, for each ten
S-Records that are successfully loaded, an ASCII asterisk character (*) is sent to the control
console, When an S-Record file has been successfully loaded, control returns to the D-Bug12
prompt.
The LOAD command is terminated when D-Bug12 receives an S9 end-of-file record. If the
object file being loaded does not contain an S9 record, D-Bug12 does not return its prompt and
continues to wait for the end-of-file record. Pressing the reset switch returns D-Bug12 to its
command line prompt.
restrictions:
When operating in POD mode, the LOAD command does not support standard baud rates above
38400. This is due to the overhead involved in the implementation of the custom serial protocol
required by the single-wire Background Debug Mode interface.
