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 (/).
PULL column:
IPD = Internal Pulldown resistor
IPU = Internal Pullup resistor
If the GPIO column is 'Y', then in GPIO mode, the pin is configurable as an IO unless otherwise marked.
