Signal Description
VDD_IO
25
Supply
I/O Power — This pin supplies 3.3V power to the chip I/O interface.
VSS_IO
14
Supply
VSS — These pins provide ground for chip logic and I/O drivers.
VSS_IO
26
VDDA
8
Supply
ADC Power — This pin supplies 3.3V power to the ADC modules. It
must be connected to a clean analog power supply.
VSSA
9
Supply
ADC Analog Ground — This pin supplies an analog ground to the
ADC modules.
VCAP
24
Supply
VCAP — Connect a 2.2 μF or greater bypass capacitor between this
pin and VSS_IO, which is required by the internal voltage regulator
for proper chip operation. See Section 10.2.1.

Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
Receive Data — SCI receive data input.
Serial Data — This pin serves as the I2C serial data line.
Clock Input — This pin serves as an optional external clock input.
After reset, the default state is GPIOB6. The alternative peripheral
functionality is controlled via the SIM (See Section 6.3.8) and the
CLKMODE bit of the OCCS Oscillator Control Register.
1. This signal is also brought out on the GPIOB1 pin.
