The "run" command lets you execute a program in memory. Entering
the "run" command by itself causes the emulator to begin executing at
the current program counter address. The "run from" command allows
you to specify an address at which execution is to start.
The "run from transfer_address" command specifies that the emulator
start executing at a previously defined "start address". Transfer
addresses are defined in assembly language source files with the .END
assembler directive (i.e., pseudo instruction). For example, the sample
program defines the address of the label Init as the transfer address.
The following command will cause the emulator to execute from the
address of the Init label.
run from transfer_address <RETURN>
The "run from reset" command specifies that the emulator begin
executing from target system reset (see "Running From Reset" section
in the "In-Circuit Emulation" chapter).
