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.
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.
