CAUTION:
Pins PD5–PD0 can be used for general-purpose I/O signals. These pins alternately
serve as the serial communication interface (SCI) and serial peripheral interface
(SPI) signals when those subsystems are enabled.
Use port E for general-purpose or analog-to-digital (A/D) inputs.
If high accuracy is required for A/D conversions, avoid reading port E during
sampling, as small disturbances can reduce the accuracy of that result.

PD0 is the receive data input (RxD) signal for the SCI.
PD1 is the transmit data output (TxD) signal for the SCI.
PD5–PD2 are dedicated to the SPI:
