pile, initiate and complete the download, and return to the monitor, all from one terminal.
This is convenient for downloading, because a single control sequence issues a carriage
return to the host and issues a download command to the PmT1 and PmE1.
call
allows execution of a program after a download from one of the board’s interfaces. This
command allows up to eight arguments to be passed to the called address from the com-
mand line. Arguments can be symbolic, numeric, characters, flags, or strings. The default
numeric base is hexadecimal.
If the application wants to return to the monitor, it should save and restore the processor
registers. Also, it is important that special-purpose registers remain unchanged.

size (unsigned long), a checksum (unsigned long) that is the long word sum of the
memory bytes of the data section.
