Function
Causes the channel's Configuration Word to be
transferred to the requesting channel.
During the Response cycle (Second Half Read) the
MTC will return in bits 8-23 of the Address Bus the
same data that was received in bits 0-15 of the Data
Bus during the Instruction cycle. After the comple-
tion of a read operation, the contents of the Con-
figuration Word register reflect the status of that
transfer with respect to the physical block read.

Function
Causes the channel's interrupt level to be trans-
ferred to the requesting channel. The level value
WIll
be placed on Data Bus bits 10 through 15 with
bit 15 as the least significant bit. This quantity
is the value previously received in the Output
Interrupt Control instruction or a default value of
00. The default value is the interrupt level assumed
by the channel when initialized. Note that the chan-
nel number returned in bits 0-9 of the Data Bus
might be different from the channel number of the
CP executing this instruction if more than one CP is
attached to the Bus.
During the Response cycle (Second Half Read),
the MTC will return in bits 8-23 of the Address Bus
the same data that was received in bits 0-15 of the
Data Bus during the request cycle.

Function
Causes the Task Word of the referenced channel
to be transferred to the requesting channel. The
Task Word transferred will contain the code for the
last operation executed by the channel (unless an
Initialize has occurred).
During the Response cycle (Second Half Read),
the MTC will return in bits 8-23 of the Address Bus
the same data that was received in bits 0-15 of the
