Technical Data

Alternate function:
Address:
Port pin function is mode dependent. Do not confuse pin function with
the electrical state of the pin at reset. Port pins are either driven to a
specified logic level or are configured as high-impedance inputs. I/O pins
configured as high-impedance inputs have port data that is
indeterminate.
In port descriptions, an I indicates this condition. Port pins that are driven
to a known logic level during reset are shown with a value of either 1 or 0.
Some control bits are unaffected by reset. Reset states for these bits are
indicated with a U.
Port A shares functions with the timer system and has:
