EPI module 0 signal 31.
PhB1
I
TTL
QEI module 1 phase B.
C11
USB0DM
I/O
Analog Bidirectional differential data pin (D- per USB specification) for
USB0.
C12
USB0DP
I/O
Analog Bidirectional differential data pin (D+ per USB specification) for
USB0.
D1
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
D2
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
VDDC
D3
-
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 25-6 on page 1150 .
PH3
I/O
TTL
GPIO port H bit 3.
EPI0S0
D10
Fault0
I/O
TTL
EPI module 0 signal 0.
I
TTL
PWM Fault 0.
PhB0
I
TTL
QEI module 0 phase B.
PH2
I/O
TTL
GPIO port H bit 2.
C1o
O
TTL
Analog comparator 1 output.
D11
EPI0S1
I/O
TTL
EPI module 0 signal 1.
Fault3
I
TTL
PWM Fault 3.
IDX1
I
TTL
QEI module 1 index.
PB1
I/O
TTL
GPIO port B bit 1. This pin is not 5-V tolerant.
CCP1
I/O
TTL
Capture/Compare/PWM 1.
D12
CCP2
PWM3
I/O
TTL
Capture/Compare/PWM 2.
O
TTL
PWM 3. This signal is controlled by PWM Generator 1.
U1Tx
O
TTL
UART module 1 transmit. When in IrDA mode, this signal has IrDA
modulation.
E1
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
E2
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
LDO
E3
-
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).
E10
VDD
-
Power Positive supply for I/O and some logic.
PB3
I/O
TTL
GPIO port B bit 3.
