8.2 Functional Description
Important: All GPIO pins are inputs by default (GPIODIR=0 and GPIOAFSEL=0), with the
exception of the five JTAG pins (PB7 and PC[3:0]. The JTAG pins default to their
JTAG functionality (GPIOAFSEL=1). Asserting a Power-On-Reset (POR) or an
external reset (RST) puts both groups of pins back to their default state.
