ADCAnPDCTL0 – Internal Pull-Down Resistance Control Register 0
This register specifies the channels to which the internal pull-down resistors of
the ADCAnIm pins are connected. For details, refer to Section 23.3.11 (3),
Diagnosis of Analog Input Pins.
This register is writable only when ADCAnCTL0.ADCAnCE = 0.
Access
This register can be read/written in 32-bit units.

ADCAn
PDNA[23:00]
Specifies whether an internal pull-down resistor is connected to CHm:
0: Does not connect an internal pull-down resistor
1: Connects an internal pull-down resistor
Note: The bits corresponding to the channels that are not implemented in this
product should be cleared to 0 (for the applicable bits, refer to the
Number of analog input pins fields in the table in Section 23.1, ADCA
Features).
