NOTE: Twisted-pair input default pins are as follows: DPBP/N_0 and DPAP/N_1.
1. Typical values are at 25°C, and are for design aid only, are not guaranteed, and are not subject to
2. CRS is asserted. RXD/RXDV are driven at the start of SFD (64 BT) unless Register bit 16.5 is set.
3. If Register bit 16.7 is set, CRS extends to RXDV de-assert.
