(10) This pin is shared by the ADC inputs and digital I/O pad cells.
NOTE
The ADC inputs are tolerant up to 1.8 V (see Section 5.13.5.6 for further details on the useable range of the ADC). The digital pads can tolerate
up to 3.6 V. Hence, take care to prevent accidental damage to the ADC inputs. TI recommends first disabling the output buffers of the digital I/Os
corresponding to the desired ADC channel (that is, converted to Hi-Z state), and thereafter disabling the respective pass switches (S7 [Pin 47],
S8 [Pin 48], S9 [Pin 49], and S10 [Pin 50]). For more information, see Drive Strength and Reset States for Analog-Digital Multiplexed Pins.

Table 4-4 describes the use, drive strength, and default state of analog- and digital-multiplexed pins at first-time power up and reset (nRESET
pulled low).
