Table 46-26. Analog Inputs
Table 46-27. Transfer Characteristics
Table 46-28. Pen Detection Sensitivity
The Pen Detection Sensitivity is programmable thanks to an ADC internal resistor. This resistor
is set depending on the value of PENDETSENS bitfield in ADC_ACR register, offset 0x94 in the
ADC User Interface.
