1.7.2.15 PT[7:0] — Port TI/O Signals
PT[7:0] are general-purpose input or output signals. They can have a pull-up or pull-down device selected
and enabled on per signal basis. Out of reset the pull devices are disabled .
1.7.2.16 AN[15:0] — ADC Input Signals
AN[15:0] are the analog inputs of the Analog-to-Digital Converter.
1.7.2.17 ACMP Signals
1.7.2.17.1 ACMPP — Non-Inverting Analog Comparator Input
ACMPP is the non-inverting input of the analog comparator.
1.7.2.17.2 ACMPM — Inverting Analog Comparator Input
ACMPM is the inverting input of the analog comparator.
1.7.2.17.3 ACMPO — Analog Comparator Output
ACMPO is the output of the analog comparator.
1.7.2.18 DAC Signals
1.7.2.18.1 DACU[1:0] Output Pins
These analog pins is used for the unbuffered analog output Voltages from the DAC0 and the DAC1 resistor
network output, when the according mode is selected.
1.7.2.18.2 AMP[1:0] Output Pins
These analog pins are used for the buffered analog outputs Voltage from the operational amplifier outputs,
when the according mode is selected.
1.7.2.18.3 AMPP[1:0] Input Pins
These analog input pins areused as input signals for the operational amplifiers positive input pins when the
according mode is selected.
1.7.2.18.4 AMPM[1:0] Input Pins
These analog input pins are used as input signals for the operational amplifiers negative input pin when
the according mode is selected.
