SCSI Registers 4-35
Register: 0x06
SCSI Destination ID (SDID)
Read/Write
R Reserved [7:4]
ENC Encoded Destination SCSI ID [3:0]
Writing these bits set the SCSI ID of the intended initiator
or target during SCSI reselection or selection phases,
respectively. When executing SCRIPTS, the SCRIPTS
processor writes the destination SCSI ID to this register.
The SCSI ID is defined by the user in a SCRIPTS Select
or Reselect instruction. The value written is the
binary-encoded ID. The priority of the 16 possible IDs, in
descending order, is:
Register: 0x07
General Purpose (GPREG0)
Read/Write
Reads to this register will always yield the same values. A write to this
register will cause the data written to be output to the appropriate GPIO
pin if it is set to the output mode in the General Purpose Pin Control Zero
(GPCNTL0) register.
R Reserved [7:5]
GPIO General Purpose I/O [4:0]
These bits are programmed through the General Purpose
Pin Control Zero (GPCNTL0) register as inputs, outputs,
or to perform special functions. As an output, these pins
can be used to enable or disable external terminators. It
