-
PWM output pin power. This 3.3V supply is used for the PWM pad drivers. Internally connected
to RVDD.
-
Analog oscillator output to slave D2-71x83 devices. OSCOUT drives a buffered version of the
crystal oscillator signal from the XTALI pin.
-
PLL Analog ground
-
Factory test use only. Must be tied low.
-
Factory test use only. Must be tied low.
-
Crystal oscillator analog input port. An external clock source would be driven into the this port.
In multi-D2-71x83 systems, the OSCOUT from the master D2-71x83 would drive the XTALI pin.
-
Crystal oscillator analog output port. When using an external clock source, this pin must be
open. XTALO does not have a drive strength specification.
-
PLL Analog power, 1.8V
-
Analog power for internal ADC, 3.3V
-
Analog input 1 to internal ADC
-
Analog voltage reference output. Must be de-coupled to analog ground with 1µF capacitor.
-
Analog input 0 to internal ADC
Analog ground for internal ADC
-
Factory test only. Must be tied high at all times.

SPI slave select I/O.
-
Digital pad ring power, 3.3V. This 3.3V supply is used for all the digital I/O pad drivers and
receivers, except for the analog pads. Internally connected to PWMVDD.
-
Digital pad ring ground. Internally connected to PWMGND.
