Multi-Function pins. Each mf pin internally drives different configuration

functions. The functions of the five mf inputs are as shown in the table below.

The logic level of mf0-4 will determine the value that the affected bits will have

upon reset of the STE100P. The operating functions of cfg0, cfg1, and fde change

depending on the state of mf0 (Auto-Negotiation enabled or disabled). Table 2

shows the relationship between cfg0, cfg1 and fde.

6fde

Full-Duplex Enable.

When A/N is enabled, fde determines full-duplex advertisement capability in

combination with cfg0 and cfg1. (See Table 2)

When A/N is disabled, fde directly affects full-duplex operation and determines

the value of PR0 bit 8 (Full/Half Duplex Mode Select).

When fde is High, full-duplex is enabled and PR0:8 = 1.

When fde is Low, full-duplex is disabled and PR0:8 = 0.
