† NC = No internal connection
‡ DVDD is the power supply for the I/O pins while CVDD is the power supply for the core CPU. VSS is the ground for both the I/O
pins and the core CPU.
§ Pin configuration shown for nonmultiplexed mode only. See the Pin Assignments for the TMS320VC5420PGE table for multiplexed
functions of specific pins.
