All registers in the 8/16 LP-LVDS physical layer specification extended features data structure can

be read and written.

14A. DETAIL: Port maintenance block header 0 CSR; reset value is implementation-dependent

(read only)

14B. DETAIL Port maintenance block header 0 CSR has the proper Extended Features block ID

14C. DETAIL: Port link time-out control CSR; reset value is 0xFFFF_FFFF

14D. DETAIL: Port response time-out control CSR; reset value is 0xFFFF_FFFF (end point devices

only)

14E. DETAIL: Port general control CSR; reset value is implementation dependent

14F. DETAIL: Port 0 error and status CSR; reset value is 0x0000_0001

14G. DETAIL: Port 0 control CSR; reset value is implementation dependent

Device follows system initialization and exploration inter-operability procedure

15A. ACTION: End point agent device that contains a boot ROM is initially assigned base device

ID = 0xFE at power-on reset

15B. ACTION: End point agent device without a boot ROM is initially assigned base device

ID = 0xFF at power-on reset

15C. ACTION: System host device is initially assigned a non-reserved base device ID at power-on

reset (end point device only)

15D. ACTION: Host device sets PGCCSR[D] at power-on reset (end point device only)

15E. ACTION: Agent device resets PGCCSR[D] at power-on reset (end point device only)

15F. ACTION: Host device sets the master enable bit (PGCCSR[M]) at power-on reset (end point

device only)

15G. ACTION: Agent device resets the master enable bit (PGCCSR[M]) at power-on reset (end

point device only)

15H. ACTION: End point device responds to all received maintenance request packets

15I. ACTION: Device with switch functionality defaults route information to allow boot ROM access

by system host

15J. ACTION: Switch device sends maintenance responses that it generates to the port that the

maintenance request was received on
