Operand Data: A single operand is data to be written to the memory location. Byte data is sent as
a 16-bit word, justified in the least-significant byte; 16- and 32-bit operands are
sent as 16 and 32 bits, respectively.
Result Data: Command complete status (0xFFFF) is returned when the register write is
complete. A value of 0x0001 (with S set) is returned if a bus error occurs.
36.4.1.5.7 Resume Execution (
The pipeline is flushed and refilled before normal instruction execution resumes. Prefetching begins at the
current address in the PC and at the current privilege level. If any register (such as the PC or SR) is altered
by a BDM command while the processor is halted, the updated value is used when prefetching resumes.
If a command issues and the CPU is not halted, the command is ignored.
