, PTV15P, PTV15N, and HHV15EN pins
HHV15EN AF13 I can be NC or connected directly to V
SS
(GND) to save power.
However, connecting these pins in this way will prevent
boundary-scan from functioning on the RGMII pins of the EMAC.
To preserve boundary-scan functionality on the RGMII pins, see
Section 7.3.3.
