Table 24-7. Signals by Pin Number (continued)
Pin Number
Pin Name
Pin Type Buffer Type^a Description
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.
Fault0
I
TTL
PWM Fault 0.
E11
Fault3
I
TTL
PWM Fault 3.
I2C0SDA
I/O
OD
I²C module 0 data.
USB0PFLT
I
TTL
Optionally used in Host mode by an external power source to
indicate an error state by that power source.
PB0
I/O
TTL
GPIO port B bit 0. This pin is not 5-V tolerant.
CCP0
I/O
TTL
Capture/Compare/PWM 0.
PWM2
O
TTL
PWM 2. This signal is controlled by PWM Generator 1.
U1Rx
E12
I
TTL
UART module 1 receive. When in IrDA mode, this signal has IrDA
modulation.
USB0ID
I
Analog This signal senses the state of the USB ID signal. The USB PHY
enables an integrated pull-up, and an external element (USB
connector) indicates the initial state of the USB controller (pulled
down is the A side of the cable and pulled up is the B side).

No connect. Leave the pin electrically unconnected/isolated.
F2
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
