DESCRIPTION
NAME NO.
Reserved. This pin must be connected to ground (V
SS
) via a 200-Ω resistor for
proper device operation.
NOTE: If the RGMII mode of the EMAC is not used, the DV
DD15
, V
REFHSTL
,
RSV13 F2 RSV13, and RSV14 pins can be connected to directly ground (V
SS
) to save
power. However, connecting these pins directly to ground will prevent
boundary-scan from functioning on the RGMII pins of the EMAC. To preserve
boundary-scan functionality on the RGMII pins, see Section 7.3.4.
Reserved. This pin must be connected to the 1.5/1.8-V I/O supply (DV
DD15
) via
a 200-Ω resistor for proper device operation.
NOTE: If the RGMII mode of the EMAC is not used, the DV
DD15
, V
REFHSTL
,
RSV14 F1 RSV13, and RSV14 pins can be connected to directly ground (V
SS
) to save
power. However, connecting these pins directly to ground will prevent
boundary-scan from functioning on the RGMII pins of the EMAC. To preserve
boundary-scan functionality on the RGMII pins, see Section 7.3.4.
Reserved. This pin must be connected via a 39-Ω resistor directly to ground
RSV15 T1 (V
SS
) for proper device operation. The resistor used should have a minimal
rating of 1/10 W.
Reserved. This pin must be connected via a 20-Ω resistor directly to 3.3-V I/O
RSV16 T2 Supply (DV
DD33
) for proper device operation. The resistor used should have a
minimal rating of 1/10 W.

) via a 1-
RSV34 E6
kΩ resistor for proper device operation.
Reserved. This pin must be connected directly to ground for proper device
RSV35 D6
operation.
