VREF—Analog reference voltage for ADC. Must be set to
V
DDA
Transmit Data (TXD0)—SCI0 transmit data output
Port B GPIO—This pin is a General Purpose I/O (GPIO) pin that
can be individually programmed as an input or output pin.
After reset, the default state is SCI output.
Receive Data (RXD0)—SCI0 receive data input
Port B GPIO—This pin is a General Purpose I/O (GPIO) pin that
can be individually programmed as an input or output pin.
After reset, the default state is SCI input.
TD0-2—Timer D Channel 0-2
Port A GPIO—This pin is a General Purpose I/O (GPIO) pin that
can be individually programmed as an input or output pin.
After reset, the default state is the quad timer input.
-0.3V for optimal performance.
