11 / 77 page DM9102A Single Chip Fast Ethernet NIC controller Final 11 Version: DM9102A-DS-F03 August 28, 2000 When The DM9102A will use this pin to serially write opcodes, addresses and data into the EEPROM. 79 MA4/EECK O Boot ROM address output/EEPROM serial clock This is multiplexed pin used by MA4 and EECK . This pin provides the clock for the EEPROM data transfer. 80 MA5 O Boot ROM address output signal 81 MA6/SELROM O/LI Boot ROM address output/Multiplex or Direct mode selection This multiplexed pin acts as boot ROM address output bus during normal operation. When RST# is active, it is used as multiplex and direct mode selection : 0 = Boot ROM interface is in multiplex mode (default) 1 = Boot ROM interface is in direct mode. 83,84,85 MA7~MA9 O Boot ROM address output bus 87 MA10/LINK&ACT# O Boot ROM address output signal/Link & Active LED In DIR mode, this pin represents the Boot ROM address bit 10 when at the time of boot ROM operation. When Boot ROM is not accessed, this pin acts as traffic-and- link led in LED MODE 0 or traffic led in LED MODE 1. 88 MA11/FDX# O Boot ROM address output/Full-duplex LED In DIR mode, this pin represents the Boot ROM address bit 11 when at the time of boot ROM operation. When Boot ROM is not accessed, this pin acts as full-duplex led. 89 MA12 / SPEED100# O Boot ROM address output/ 100Mbps LED In DIR mode, this pin represents the Boot ROM address bit 12 when at the time of boot ROM operation. When Boot ROM is not accessed, this pin acts as speed-100 led. 90 MA13/SPEED10# O Boot ROM address output signal/10Mbps LED In DIR mode, this pin represents the Boot ROM address bit 13 when at the time of boot ROM operation. When Boot ROM is not accessed, this pin acts as speed-10 led. 91,92,93, 94 MA14~MA17 O Boot ROM address output bus LED Pins (Please refer to p.11 “NOTE: LED Mode” for details.) Pin No. 128QFP/128TQFP Pin Name I/O Description 87 LINK&ACT# / ACT# O LED output pin, active low mode 0 = Link and traffic LED. Active low to indicate normal link, and it will flash as a traffic LED when transmitting or receiving. mode 1 = traffic LED only 88 FDX# / FDX# O LED output pin, active low mode 0 = Full duplex LED mode 1 = Full duplex LED 89 SPEED100# / SPEED100# O LED output pin, active low mode 0 = 100Mbps LED mode 1 = 100Mbps LED |
