Chip Information
Bits 4:1 — CL-PD67XX Revision Level
This field identifies the revision of the controller. The initial value is ‘111’. Contact Cirrus Logic for
more information on revision levels for the CL-PD6710 and CL-PD6722.
Bit 5 — Dual/Single Socket*
This bit specifies the number of sockets supported by the CL-PD67XX.
Bits 7:6 — Cirrus Logic Host-Adapter Identification
This field identifies a Cirrus Logic host-adapter device. After chip reset or doing an I/O write to this
register, the first read of this register will return ‘11’. On the next read, this field will be ‘00’. This
pattern of toggling data on subsequent reads can be used by software to determine presence of
a Cirrus Logic host adapter in a system or to determine occurrence of a device reset.
a
The value for CL-PD6710 is ‘0’, and the value for CL-PD6722 is ‘1’.
b
This read-only value depends on the revision level of the CL-PD67XX chip.
c
The value for CL-PD6722 is ‘1’. The value for the CL-PD6710 is ‘0’.
