Description
Internal power and ground generated by internal regulator
External power and ground, supply to pin drivers and internal
voltage regulator.
External power and ground, supply to pin drivers.
Operating voltage and ground for the analog-to-digital
converters and the reference for the internal voltage regulator,
allows the supply voltage to the A/D to be bypassed
independently.
Reference voltages for the analog-to-digital converter.
Provides operating voltage and ground for the Phased-Locked
Loop. This allows the supply voltage to the PLL to be bypassed
independently. Internal power and ground generated by internal
regulator.
Internal Voltage Regulator enable/disable
