nBP register (register 21)
The nBP register defines back-pressure flow control
capability for each port. Table-7.21 describes all the
bit of this register.
nPORT register (register 22)
The nPORT register is used to isolate ports from the
network. Setting the associated bit in this register will
stop a port from receiving or transmitting any frame.
Table-7.22 describes all the bits of this register.
