Description
BK_EN
IPH/O
Backpressure enable
1: enable (default), 0: disable
This pin is input to set backpressure during reset. It becomes an output signal
MRXD2 after reset, if external MII port is enabled.
IPL/O
Backpressure type selection
00: carrier base backpressure (default)
01: (reserved)
10: (reserved)
These two pins are input during reset. It becomes output signals MRXD0 and
MRXD1 after reset, if external MII port is enabled. IP178A supports carrier base
backpressure only.
IPH/O
IEEE 802.3x flow control enable
1: enable (default), 0:disable
This pin is an input to set flow control during reset. It becomes an output signal
MCOL after reset, if external MII port is enabled.

BF_STM_EN
IPL
Broadcast storm enable
1: enable, 0: disable (default)
IP178A drops the incoming packet if the number of broadcast packet in queue is
over the threshold.
Drop the transmitting packet after 16 consecutive collisions
1: drop, 0: not drop (default)
Turn on twopartD (Twopart)
1: enable (fixed), 0: disable
IP178A examine the carrier for 64 bits only during its back off period if this
function is enabled. It makes IP178A have higher priority in a collision event.
IP178A uses the default value. User can’t change the setting.
IPH/O
Aggressive back off enable (MODBCK)
IP178A uses modified (aggressive) back off algorithm if this function is enabled.
The maximum back off period is limited to 8-slot time. It makes IP178A have
higher priority in a collision event.
1: aggressive mode enable (default),
0: standard back off
It is link LED of port 4 after reset if LED direct mode is selected.
IPL/O It is for testing only. This pin should be left open to turn off the function for normal
operation.
It is link LED of port 5 after reset if LED direct mode is selected.
