Other Parts Discussed in Thread: DP83869
We're using the DP83869HM in bridge mode (RGMII to SGMII).
Datasheet page 95(dp83869hm.pdf) describes the two-supply configuration option. On page 96, it states to strap the SUPPLYMODE_SEL (pin 23) low. Pin 23 is JTAG_TMS, does this device require strapping to use the two-supply configuration?
