This instruction requires two longword operands. The first selects the
register to which the operand data is to be written; the second
contains the data.
Successful write operations return 0xFFFF. Bus errors on the write
cycle are indicated by the setting of bit 16 in the status message and
by a data pattern of 0x0001.
