SUPPLY VOLTAGE MONITOR PINS
Die-side core supply (CV
DD
) 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, see
CV
DDMON
AE9
the TMS320C6472/TMS320TCI6486 Hardware Design Guide
application report (literature number SPRAAQ4). If the CV
DDMON
pin is not used, it should be connected directly to the die-side
core supply (CV
DD
).
Die-side 1.5-/1.8-V I/O supply (DV
DD15
) 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, see the TMS320C6472/TMS320TCI6486
Hardware Design Guide application report (literature number
SPRAAQ4). If the DV
DD15MON
pin is not used, it should be
DV
DD15MON
AG13 connected directly to the 1.5-/1.8-V I/O supply (DV
DD15
).
NOTE: If the RGMII mode of the EMAC is not used, the DV
DD15
,
DV
DD15MON
, V
REFHSTL
, PTV15P, PTV15N, and HHV15EN pins
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.
Die-side 1.8-V I/O supply (DV
DD18
) 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, see the TMS320C6472/TMS320TCI6486
Hardware Design Guide application report (literature number
SPRAAQ4). If the DV
DD18MON
pin is not used, it should be
connected directly to the 1.8-V I/O supply (DV
DD18
).

prevents boundary scan from functioning on the DDR2 Memory
Controller pins. To preserve boundary-scan functionality on the
DDR2 Memory Controller pins, see Section 7.3.3.
Die-side 3.3-V I/O supply (DV
DD33
) 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
DV
DD33MON
V5
monitoring pins, see the TMS320C6472/TMS320TCI6486
Hardware Design Guide application report (literature number
SPRAAQ4). If the DV
DD33MON
pin is not used, it should be
connected directly to the 3.3-V I/O supply (DV
DD33
).
