13 / 106 page  Micrel KS8893M/ML/MI June 2005 13 M9999-063005 Pin Number Pin Name Type (1) Description 9 NC Ipd No connect 10 NC Ipd No connect 11 NC Ipu No connect 12 ADVFC Ipu 1 = advertise the switch’s flow control capability via auto negotiation. 0 = will not advertise the switch’s flow control capability via auto negotiation. 13 P2ANEN Ipu 1 = enable auto negotiation on port 2 0 = disable auto negotiation on port 2 14 P2SPD Ipd 1 = force port 2 to 100BT if P2ANEN = 0 0 = force port 2 to 10BT if P2ANEN = 0 15 P2DPX Ipd 1 = port 2 default to full duplex mode if P2ANEN = 1 and auto negotiation fails. Force port 2 in full duplex mode if P2ANEN = 0. 0 = port 2 default to half duplex mode if P2ANEN = 1 and auto negotiation fails. Force port 2 in half duplex mode if P2ANEN = 0. 16 P2FFC Ipd 1 = always enable (force) port 2 flow control feature 0 = port 2 flow control feature enable is determined by auto negotiation result. 17 NC Opu No connect 18 NC Ipd No connect 19 NC Ipd No connect 20 P2LED3 Opd Port 2 LED indicator Note: Internal pull-down is weak; it will not turn ON the LED. See description in pin 4. 21 DGND Gnd Digital ground 22 VDDC / VOUT_1V2 P VDDC: For KS8893M, this is an input power pin for the 1.2V digital core VDD. VOUT_1V2: For KS8893ML, this is a 1.2V output power pin to supply the KS8893ML’s input power pins: VDDAP (pin 63), VDDC (pins 91 and 123), and VDDA (pins 38, 43, and 57). 23 LEDSEL1 Ipd LED display mode select See description in pins 1 and 4. 24 NC O No connect 25 P1LED3 Opd Port 1 LED indicator Note: An external 1K pull-down is needed on this pin if it is connected to a LED. The 1K resistor will not turn ON the LED. See description in pin 1. Note: 1. P = Power supply. Gnd = Ground. O = Output. Ipu = Input w/ internal pull-up. Ipd = Input w/ internal pull-down. Opu = Output w/ internal pull-up. Opd = Output w/ internal pull-down. |
