Buffer Type^a Description
TTL
GPIO port E bit 3.
Analog Analog-to-digital converter input 0.
TTL
Capture/Compare/PWM 1.
TTL
Capture/Compare/PWM 7.
TTL
QEI module 0 phase B.
TTL
SSI module 1 transmit.
TTL
GPIO port E bit 2.
Analog Analog-to-digital converter input 1.
TTL
Capture/Compare/PWM 2.
TTL
Capture/Compare/PWM 4.
TTL
QEI module 0 phase A.
TTL
SSI module 1 receive.
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 24-2 on page 1072, 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 1.
Analog Analog-to-digital converter input 2.
TTL
Capture/Compare/PWM 2.
TTL
Capture/Compare/PWM 6.
TTL
PWM Fault 0.
TTL
PWM 5. This signal is controlled by PWM Generator 2.
TTL
SSI module 1 frame.
TTL
GPIO port E bit 0.
Analog Analog-to-digital converter input 3.
TTL
Capture/Compare/PWM 3.
TTL
PWM 4. This signal is controlled by PWM Generator 2.
TTL
SSI module 1 clock.
TTL
Optionally used in Host mode by an external power source to
indicate an error state by that power source.
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).
