DESCRIPTION
NAME
NO.
Reserved. This pin must be connected to the 1.8-V I/O supply (DV
DD18
) via a
200-
Ω
resistor for proper device operation.
NOTE: If the DDR2 Memory Controller is not used, the V
REFSSTL
, RSV11, and
RSV12 pins can be connected directly to ground (V
SS
) to save power.
RSV12
C24
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
