5.95 Port Reset Option CSR n (SPn_RST_OPT)

Each of the four ports is supported by a register of this type (see Table 180). SPn_RST_OPT is shown in Figure 158 and described in Table 181.

Table 180. SPn_RST_OPT Registers and the Associated Ports

Register	Address Offset	Associated Port
SP0_RST_OPT	14000h	Port 0
SP1_RST_OPT	14100h	Port 1
SP2_RST_OPT	14200h	Port 2
SP3_RST_OPT	14300h	Port 3

Table 181. Port Reset Option CSR n (SPn_RST_OPT) Field Descriptions

Bit	Field	Value	Description
31–8	Reserved	0	These read-only bits return 0s when read.
7–0	PORT_ID		Port ID defines unique number for port in Switch. The Port ID is used for port-write request. The ID
			coincides with ISF port of connection. Example: 00_0000_01 _ port 1 ( Impl.: IP0, port 1)
			00_0001_11 _ port 7 ( Impl.: IP1, port 3).
