MS ADDR
This two-operand instruction requires a longword absolute address
that specifies a location to which the data operand is to be written.
Byte data is sent as a 16-bit word, justified in the LSB; 16- and 32-bit
operands are sent as 16 and 32 bits, respectively
Command complete status is indicated by returning 0xFFFF (with S
cleared) when the register write is complete. A value of 0x0001 (with
S set) is returned if a bus error occurs.
