21 / 116 page  Micrel, Inc. KSZ8893MQL/MBL February 2010 21 M9999-021110-1.6 Ball Number Ball Name Type (1) Ball Function Description A8 P2SPD Ipd 1 = force port 2 to 100BT if P2ANEN = 0 0 = force port 2 to 10BT if P2ANEN = 0 B7 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. A7 P2FFC Ipd 1 = always enable (force) port 2 flow control feature 0 = port 2 flow control feature enable is determined by auto- negotiation result. B6 P2LED3 Opd Port 2 LED indicator Note: Internal pull-down is weak; it will not turn ON the LED. See description in pin 4. A6 LEDSEL1 Ipd LED display mode select See description in pins 1 and 4. B5 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. A5 RMII_EN Opd Strap pin for RMII Mode 0 = Disable 1 = Enable After reset, this pin has no meaning and is a no connect. B4 HWPOVR Ipd Hardware pin overwrite 0 = Disable. All strap-in pins configurations are overwritten by the EEPROM configuration data 1 = Enable. All strap-in pins configurations are overwritten by the EEPROM configuration data, except for register 0x2C bits [7:5], (port 2: auto-negotiation enable, force speed, force duplex). A4 P2MDIXDIS Ipd Port 2 Auto MDI/MDI-X PD (default) = enable PU = disable B3 P2MDIX Ipd Port 2 MDI/MDI-X setting when auto MDI/MDI-X is disabled. PD (default) = MDI-X (transmit on TXP2 / TXM2 pins) PU = MDI, (transmit on RXP2 / RXM2 pins) A3 P1ANEN Ipu 1 = enable auto-negotiation on port 1 0 = disable auto-negotiation on port 1 B2 P1SPD Ipd 1 = force port 1 to 100BT if P1ANEN = 0 0 = force port 1 to 10BT if P1ANEN = 0 A2 P1DPX Ipd 1 = port 1 default to full duplex mode if P1ANEN = 1 and auto- negotiation fails. Force port 1 in full-duplex mode if P1ANEN = 0. 0 = port 1 default to half duplex mode if P1ANEN = 1 and auto- negotiation fails. Force port 1 in half duplex mode if P1ANEN = 0. |
