Demo Board for 10/100 and 100BASE-FX Applications — LXD970A

4.1.2Additional Jumper Functions

In addition to the MF pins, the Hardware Control Interface (JP1) contains 10 pins, (#41 - #50) that are labeled as MAN0, MAN1, MAN2, TRSTE and MDDIS, (Note: TRSTE and MDDIS are not labeled on the demo board). MAN0 = CFG0, MAN1 = FDE and MAN2 = CFG1. The Manual pins control the status of the applicable function by installing or removing a jumper. See Table 6 for function status.
