Command Sequence:
Operand Data:
Result Data:
5.6.2.8.13 Call User Code (CALL). This instruction provides a convenient way to patch
user code. The return PC is stacked at the location pointed to by the current SP. The
stacked PC serves as a return address to be restored by the RTS command that
terminates the patch routine. After stacking is complete, the 32-bit operand data is loaded
into the PC. The pipeline is flushed and refilled from the location pointed to by the new
PC, BDM is exited, and normal mode instruction execution begins.

If a bus error or address error occurs during return address
stacking, the CPU returns an error status via the serial
interface and remains in BDM.
If a bus error or address error occurs on the first instruction
prefetch from the new PC, the processor exits BDM and the
error is trapped as a normal mode exception. The stacked
value of the current PC may not be valid in this case,
depending on the state of the machine prior to entering BDM.
For address error, the PC does not reflect the true return PC.
Instead, the stacked fault address is the (odd) return PC.
