IP113
PIN Description
(continued)
Pin no.
LED pins used as initial setting mode during reset
Note:
Please refer to the paragraph of Initial Value Set Via Pins for detail information about pull high/ low setting.
86
X_EN
1: enable (default),
0: disable
It is internally pulled high.
92
BK_EN
IPH
Backpressure enable (BK_EN)
1: enable (default),
0: disable
It is internally pulled high.
90
AGING
1: enable, aging time 300s (default),
0: disable
It is internally pulled high.
88
R4_EN
A full duplex port will change its capability to half duplex, if the
remote full duplex port does not support IEEE802.3x and this
function is enabled.
1: enable, 0: disable (default)
It is internally pulled low.

OP[0]
OP[1:0] should be connected to VCC through resistors.
MODE should be connected to GND through resistors.
77,78
BP_KIND[1:0]
IPL
Backpressure type selection
Bp_kind[1:0] are valid only if Bk_en is set to high.
00: carrier base backpressure (default)
01: collision base backpressure with hashing
10: collision base backpressure without hashing
After reset, IP113 reads EEPROM with BP_KIND[1:0], which
works as EEDO and EEDI. BP_KIND[1] is an input signal and
BP_KIND[0] is an output signal during reading EEPROM. After
finishing reading EEPROM, these two pins becomes input
signal to isolate IP113 from EEPROM.
