1. Type Column Coding: I = Input, O = Output, OD = Open Drain output, ST = Schmitt Triggered input, TS =
Three-State-able output, SL = Slew-rate Limited output, IP = weak Internal Pull-up, ID = weak Internal pull-
Down.
2. The IP/ID resistors are disabled during H/W Power-Down mode. If a Pin is an output or an I/O, the IP/ID
resistors are also disabled when the output is enabled.
3. RxData[0:7]_0, RxData[0:7]_1, CRS_DV[0:7] and RxER[0:7] outputs are three-stated in Isolation and H/W
Power-Down modes and during H/W reset.
