Operand Data:
A single operand is data to be written to the memory location. Byte data is transmitted as a 16-bit word,
justified in the least significant byte; 16- and 32-bit operands are transmitted as 16 and 32 bits, respectively.
Result Data:
Command complete status is indicated by returning the data $FFFF (with the status bit cleared) when the
register write is complete. A value of $0001 (with the status bit set) is returned if a bus error occurs.
20.3.4.1.7
The GO command flushes and refills the pipeline before resuming normal instruction execution.
Prefetching begins at the current PC and current privilege level. If any register (For example, the PC or
SR) was altered by a BDM command while halted, the updated value is used as the prefetching resumes.
