READ
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.
