Description
Exposed Pad. The LFCSP_VQ only has an exposed paddle that must be left
unconnected.
Single-Ended or Differential Analog Input 0.
Single-Ended or Differential Analog Input 1.
Single-Ended or Differential Analog Input 2/Comparator Positive Input.
Single-Ended or Differential Analog Input 3/Comparator Negative Input.
General-Purpose Input and Output Port 2.4/ADC Single-Ended or
Differential Analog Input/Programmable Logic Array Input Element 10.
By default, this pin is configured as a digital input with a weak pull-up
resistor enabled.
General-Purpose Input and Output Port 2.3/ADC Single-Ended or
Differential Analog Input 8/Programmable Logic Array Output Element 7.
By default, this pin is configured as a digital input with a weak pull-up
resistor enabled. When used as ADC input, pull-up resistor should be
disabled manually.
General-Purpose Input and Output Port 2.2/ADC Single-Ended or
Differential Analog Input 7/PWM Sync /Programmable Logic Array Output
Element 6. By default, this pin is configured as a digital input with a weak
pull-up resistor enabled. When used as ADC input, pull-up resistor should
be disabled manually.
General-Purpose Input and Output Port 2.0/ADC Single-Ended or
Differential Analog Input 12/PWM Output 4/Programmable Logic Array
Input Element 7. By default, this pin is configured as a digital input with a
weak pull-up resistor enabled. When used as an ADC input, it is not
possible to disable the internal pull-up resister. This means that this pin
has a higher leakage current value than other analog input pins.
Ground Voltage Reference for the ADC. For optimal performance, the
analog power supply should be separated from DGND.
DAC0 Voltage Output or ADC Input.
DAC1 Voltage Output or ADC Input.
