39 / 58 page  DocID028515 Rev 1 39/58 STCOM Pinout and pin description 58 2.2 GPIOs multiplexing scheme In the STCOM, peripherals are connected to I/Os through a multiplexer. At a time one single peripheral can control the I/Os. In this way, there is no conflict between peripherals sharing the same I/O pins. Thanks to a set of configuration registers, the user can select one of the 4 possible alternate functions for each pin as described in Table 8. Table 8.
