The MSG, C/D and I/O bits together can be referred to
as the SCSI Phase bits. They indicate the phase of the
SCSI bus. These bits may be latched or unlatched
depending on whether or not the ENF bit in Control
Register Two is set.
In the latched mode the SCSI phase bits are latched at
the end of a command and the latch is opened when the
Interrupt Status Register (INSTREG) is read. In the un-
latched mode, they indicate the phase of the SCSI bus
when this register is read.

SDIDREG – Bits 2:0 – DID 2:0 – Destination ID 2:0
The DID 2:0 bits are the encoded SCSI ID of the device
on the SCSI bus which needs to be selected or
reselected.
At power-up the state of these bits is undefined. The DID
2:0 bits are not affected by reset.
