DESCRIPTION

NAME

NO.

 

 

 

Reserved. This pin must be connected to the 1.8-V I/O supply (DVDD18) via a

 

 

200-Ωresistor for proper device operation.

 

 

NOTE: If the DDR2 Memory Controller is not used, the VREFSSTL, RSV11, and

RSV12

C24

RSV12 pins can be connected directly to ground (VSS) to save power.

 

 

However, connecting these pins directly to ground will prevent boundary-scan

 

 

from functioning on the DDR2 Memory Controller pins. To preserve

 

 

boundary-scan functionality on the DDR2 Memory Controller pins, see

 

 

Section 7.3.4.

 

 

Reserved. This pin must be connected to ground (VSS) via a 200-Ωresistor for

 

 

proper device operation.

 

 

NOTE: If the RGMII mode of the EMAC is not used, the DVDD15, VREFHSTL,

RSV13

F2

RSV13, and RSV14 pins can be connected to directly ground (VSS) 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 (DVDD15) via

 

 

a 200-Ωresistor for proper device operation.

 

 

NOTE: If the RGMII mode of the EMAC is not used, the DVDD15, VREFHSTL,

RSV14

F1

RSV13, and RSV14 pins can be connected to directly ground (VSS) 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-Ωresistor directly to ground

RSV15

T1

(VSS) 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-Ωresistor directly to 3.3-V I/O

RSV16

T2

Supply (DVDD33) for proper device operation. The resistor used should have a

 

 

minimal rating of 1/10 W.
