Description
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 VDD25 pins
at the board level in addition to the decoupling
capacitor(s).
Positive supply for I/O and some logic.
CPU Mode bit 0. Input must be set to logic 0
(grounded); other encodings reserved.
GPIO port B bit 0
Capture/Compare/PWM 0
GPIO port D bit 7
GPIO port D bit 6
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Ground reference for logic and I/O pins.
Ground reference for logic and I/O pins.
Ground reference for logic and I/O pins.
GPIO port D bit 0
GPIO port D bit 1
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Positive supply for I/O and some logic.
Positive supply for I/O and some logic.
Positive supply for I/O and some logic.
GPIO port D bit 3
UART module 1 transmit. When in IrDA mode,
this signal has IrDA modulation.
GPIO port D bit 2
UART module 1 receive. When in IrDA mode,
this signal has IrDA modulation.
Ground reference for logic and I/O pins.
Positive supply for I/O and some logic.
System reset input.
GPIO port F bit 1
XTALN of the Ethernet PHY
