(1)

This pin must always be connected via a 6.3V or greater, 0.8uF to 1.5μF capacitor to VSS if the respective VDDSHVx pin is ever

operated at 3.3V. The capacitor selected must provide a capacitance within the defined range after it has been derated for DC-bias,

operating temperature, and aging effects. There are three connection options if the respective VDDSHVx pin is only operated at 1.8V.

The pin can be connected to the same decoupling capacitor that is required for 3.3V operation, it can be left unconnected, or it can be

connected to the same 1.8V power source as the respective VDDSHVx pin.

5.3.21 PRUSS

Note

The PRUSS contains a second layer of peripheral signal multiplexing to enable additional functionality

on the PRU GPO and GPI signals. This internal wrapper multiplexing is described in the PRUSS

chapter in the device TRM
