JTAG TMS and SWDIO.
TMS
I
TTL
JTAG TMS and SWDIO.
PC0
I/O
TTL
GPIO port C bit 0.
52
SWCLK
I
TTL
JTAG/SWD CLK.
TCK
I
TTL
JTAG/SWD CLK.
53
GND
-
Power Ground reference for logic and I/O pins.
VDDC
54
-
Power Positive supply for most of the logic function, including the
processor core and most peripherals. The voltage on this pin is
1.3 V and is supplied by the on-chip LDO. The VDDC pins should
only be connected to the LDO pin and an external capacitor as
specified in Table 24-6 on page 991.
PB7
I/O
TTL
GPIO port B bit 7.
55
NMI
I
TTL
Non-maskable interrupt.
PB6
I/O
TTL
GPIO port B bit 6.
C0+
I
Analog Analog comparator 0 positive input.
C0o
O
TTL
Analog comparator 0 output.
CCP1
I/O
TTL
Capture/Compare/PWM 1.
CCP5
I/O
TTL
Capture/Compare/PWM 5.
56
Fault1
I
TTL
PWM Fault 1.
IDX0
I
TTL
QEI module 0 index.
VREFA
I
Analog This input provides a reference voltage used to specify the input
voltage at which the ADC converts to a maximum value. In other
words, the voltage that is applied to VREFA is the voltage with which
an AINn signal is converted to 1023. The VREFA input is limited
to the range specified in Table 24-23 on page 998 .
PB5
I/O
TTL
GPIO port B bit 5.
C0o
O
TTL
Analog comparator 0 output.
C1-
I
Analog Analog comparator 1 negative input.
CAN0Tx
O
TTL
CAN module 0 transmit.
57
CCP0
I/O
TTL
Capture/Compare/PWM 0.
CCP2
I/O
TTL
Capture/Compare/PWM 2.
CCP5
I/O
TTL
Capture/Compare/PWM 5.
U1Tx
O
TTL
UART module 1 transmit. When in IrDA mode, this signal has IrDA
modulation.
