DescriptionBuffer Type
a
Pin TypePin NamePin Number
No connect. Leave the pin electrically unconnected/isolated.--NCE2
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).

Positive supply for I/O and some logic.Power-VDD
E10
CPU Mode bit 0. Input must be set to logic 0 (grounded); other
encodings reserved.

PWM 2. This signal is controlled by PWM Generator 1.TTLOPWM2
UART module 1 receive. When in IrDA mode, this signal has IrDA
modulation.
TTLIU1Rx
No connect. Leave the pin electrically unconnected/isolated.--NCF1
No connect. Leave the pin electrically unconnected/isolated.--NCF2
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 23-6 on page 986 .
