7 0 Port Block Functions
7 3 PORT STATUS REGISTER FUNCTIONS
Each RIC port has its own status register In addition to
providing status concerning the port and its network seg-
ment the register allows the following operations to be per-
formed upon the port
1 Port disable
2 Link Disable
3 Partition reconnection
4 Selection between normal and reduced squelch levels
Note For recommended modules see ‘‘Ethernet Magnetics Vendors for 10BASE-T 10BASE2 and 10BASE5’’ in Section 5 of this Databook

Note that the link disable and port disable functions are mu-
tually exclusive functions i e disabling link does not affect
receiving and transmitting from to that port and disabling a
port does not disable link
When a port is disabled packet transmission and reception
between the port’s segment and the rest of the network is
prevented
