Buffer Type^a Description
TTL
GPIO port E bit 7.
Analog Analog-to-digital converter input 0.
TTL
PWM 5. This signal is controlled by PWM Generator 2.
TTL
UART module 1 Data Carrier Detect modem status input signal.
TTL
GPIO port E bit 6.
Analog Analog-to-digital converter input 1.
TTL
Analog comparator 1 output.
TTL
PWM 4. This signal is controlled by PWM Generator 2.
TTL
UART module 1 Clear To Send modem flow control input signal.
Power
The positive supply for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from VDD to minimize
the electrical noise contained on VDD from affecting the analog
functions. VDDA pins must be supplied with a voltage that meets
the specification in Table 25-2 on page 1145, regardless of system
implementation.
Power
The ground reference for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from GND to minimize
the electrical noise contained on VDD from affecting the analog
functions.
TTL
GPIO port E bit 5.
Analog Analog-to-digital converter input 2.
TTL
Capture/Compare/PWM 5.
TTL
GPIO port E bit 4.
Analog Analog-to-digital converter input 3.
TTL
Capture/Compare/PWM 2.
TTL
Capture/Compare/PWM 3.
TTL
PWM Fault 0.
TTL
UART module 2 transmit. When in IrDA mode, this signal has IrDA
modulation.
Power
Low drop-out regulator output voltage. This pin requires an external
capacitor between the pin and GND of 1 µF or greater. The LDO
pin must also be connected to the VDDC pins at the board level in
addition to the decoupling capacitor(s).
Power Positive supply for I/O and some logic.
Power Ground reference for logic and I/O pins.
