START I/O DIAGNOSE INSTHl'CTION
Under normal System/:rno operation. when a start
I/O instruction is given. bit positions 4 through 7 oJ
the channel address word (CAW) must contain zeros,
and bit positions 38 and 39 of every channel command
word (CCW) except one specifying transfer in channel
must contain zeros. If either of these restrictions is
violated, program check is stored in the channel
status word.
The start I/O diagnose instruction inhibits normal
validity checks 0f bits 4 through 7 of the CAW and bit
38 and 39 of CCW. Instead, these bits are used for
translator control. CAW bit 5 must be on
if
the start
I/O
diagnose instruction is used; otherwise, a pro-
gram check indication is stored in the channel status
word (CSW).

There is one parameter for the start I/O diagnose
instruction. The" x" in the general diagnose instruc-
tion format specifies a GPR that contains the channel
and unit address (in the low-order 11 bits) of the I/O
device to be used.
