.h). With this define the SoC pin and its desired function is specified. In the example down below for example the pin FLEXCAN0_TX is muxed to the function DMA_FLEXCAN0_TX. The third integer then defines the pin settings in hexadecimal notation. On the example below 0x00 means that Bit 0 and Bit 0 is set. Bit 0 sets high or low drive strength in this example with 0 meaning low drive strength. With Bit 0-0 the pull-up or pull-down behaviour is controlled with '00' meaning pull-up. For a detailed description and table of possible pin-settings, look them up in the Reference Manual for
