I, IO
SMI interface
The external MAC device uses the interface to program
IP113M LF. MDIO is an open drain.

ADDR[4:0]
IPL
PHY address
The external MAC device uses the address to identify
each IP113M LF in a chassis.
IP113M LF also uses ADDR[2:0] as EEPROM address
A[2:0] to read EEPROM.

OSCI, X2
I, O
Crystal pins
OSCI and X2 are connected to a 25Mhz crystal.
If a 25MHz oscillator is used, OSCI is connected to the
oscillator’s output and X2 should be left open.
26, 27
TSM, TSE
IPL
Scan pins
These two pins should be left open or connected to ground
for normal operation.

INTB
O
Interrupt
0: an interrupt happens. Its output is low.
1: no interrupt. Its output is high impedance and it needs
an external pull up resistor.
Pin no.
