SUPPLY VOLTAGE MONITOR PINS
Die-side 1.2-V core supply (CV
) voltage monitor pin. The monitor pins
indicate the voltage on the die and, therefore, provide the best probe point for
voltage monitoring purposes. For more information regarding the use of this
and other voltage monitoring pins. If the CV
pin is not used, it should be
connected directly to the 1.2-V core supply (CV
DD
).
Die-side 3.3-V I/O supply (DV
) voltage monitor pin. The monitor pins
indicate the voltage on the die and, therefore, provide the best probe point for
voltage monitoring purposes. For more information regarding the use of this
and other voltage monitoring pins. If the DV
pin is not used, it should
be connected directly to the 3.3-V I/O supply (DV
DD33
).
Die-side 1.5-/1.8-V I/O supply (DV
) voltage monitor pin. The monitor pins
indicate the voltage on the die and, therefore, provide the best probe point for
voltage monitoring purposes. For more information regarding the use of this
and other voltage monitoring pins. If the DV
pin is not used, it should
be connected directly to the 1.5-/1.8-V I/O supply (DV
).
NOTE:
If the RGMII mode of the EMAC is not used, the DV
, DV
,
V
, RSV13, and RSV14 pins can be connected directly to ground (V
)
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
.
Die-side 1.8-V I/O supply (DV
) voltage monitor pin. The monitor pins
indicate the voltage on the die and, therefore, provide the best probe point for
voltage monitoring purposes. For more information regarding the use of this
and other voltage monitoring pins. If the DV
pin is not used, it should
be connected directly to the 1.8-V I/O supply (DV
DD18
).
SUPPLY VOLTAGE PINS
(DV
/2)-V reference for SSTL buffer (DDR2 Memory Controller). This input
voltage can be generated directly from DV
DD18
using two 1-k
resistors to form
a resistor divider circuit.
NOTE:
The DDR2 Memory Controller is not used, the V
, RSV11, and
RSV12 pins can be connected directly to ground (V
) 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
