Command Sequence:
WRITE (B/W) MS ADDR
??? 'NOT READY'
WRITE (LONG) MS ADDR
??? 'NOT READY'
Operand Data: This two-operand instruction requires a longword absolute address that specifies
a location the data operand is 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.
Result Data: 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.

Subsequent commands use this address, perform the memory read, increment it by the current
DUMP
operand size, and store the updated address in the temporary register.
