(1) TYPE column refers to pin direction in functional mode. If a pin has more than one function with different directions, the functions
are separated with a slash (/).
(2) PULL column:
IPD = InternalPulldown resistor
IPU = InternalPullup resistor
(3) If the GPIO column is 'Y', then in GPIO mode, the pin is configurable as an IO unless otherwise marked.
