Ball Function
Test Enable
For normal operation, pull-down this ball to ground.
Scan Test Scan Mux Enable
For normal operation, pull-down this ball to ground.
Port 1 and Port 2 LED indicators
Notes:
1. Link = On; Activity = Blink; Link/Act = On/Blink; Full Dup/Col = On/Blink;
Full Duplex = On (Full duplex); Off (Half duplex)
Speed = On (100BASE-T); Off (10BASE-T)
2. P1LED3 is ball A4. P2LED3 is ball C6.
Port 1 and Port 2 LED indicators
Note 3: RPT_COL = Blink; RPT_Link3/RX (Host port) = On/Blink;
RPT_Link2/RX (Port 2) = On/Blink; RPT_Link1/RX (Port 1) = On/Blink;
RPT_ACT = on if any activity, RPT_ERR3/2/1 = RX error on port 3, 2, or 1.
Ready Return Not:
For VLBus-like mode: Asserted by the host to complete synchronous read
cycles. If the host doesn’t connect to this ball, assert this ball.
For burst mode (32-bit interface only): Host drives this ball low to signal waiting
states.
Bus Interface Clock
Local bus clock for synchronous bus systems. Maximum frequency is 50MHz.
