The UCSPL register defines the connected UTOPIA sub-ports within all ports for polling.
• UCSPL UCSPL[7] corresponds to sub-port 7 (CLAV7) and UCSPL[0] corresponds to sub-port 0 (CLAV0).
When a bit is set, then the sub-port is connected and will be polled; when clear, the sub-port is not connected
and will not be polled.

The UTOPIA Sub-Port Address Location register defines which byte of the PDU header the sub-port address is
contained in when using Extended UTOPIA mode. The PDU header consists of the User Prepend, the ATM cell
header and UDF bytes, and so can be a maximum of 18 bytes. The first of these bytes is denoted as byte 0. The
corresponding USPAM register is used to define which bits in the byte contain the sub-port address.
• USPAL[4:0] Byte number of the PDU header byte which contains the UTOPIA sub-port address.
