The Pin Multiplexer (PINMUX) driver provides a method - * of configuring the individual pin peripheral multiplexers to select - * alternate pin functions. - * - * \subsection asfdoc_sam0_system_pinmux_features Driver Feature Macro Definition - * <table> - * <tr> - * <th>Driver Feature Macro</th> - * <th>Supported devices</th> - * </tr> - * <tr> - * <td>FEATURE_SYSTEM_PINMUX_DRIVE_STRENGTH</td> - * <td>SAM L21, SAM C20/C21</td> - * </tr> - * </table> - * \note The specific features are only available in the driver when the - * selected device supports those features. - * - * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins - * SAM devices use two naming conventions for the I/O pins in the device; one - * physical and one logical. Each physical pin on a device package is assigned - * both a physical port and pin identifier (e.g. "PORTA.0") as well as a - * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the - * former is used to map physical pins to their physical internal device module - * counterparts, for simplicity the design of this driver uses the logical GPIO - * numbers instead. - * - * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing - * SAM devices contain a peripheral MUX, which is individually controllable - * for each I/O pin of the device. The peripheral MUX allows you to select the - * function of a physical package pin - whether it will be controlled as a user - * controllable GPIO pin, or whether it will be connected internally to one of - * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is - * configured in GPIO mode, other peripherals connected to the same pin will be - * disabled. - * - * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics - * There are several special modes that can be selected on one or more I/O pins - * of the device, which alter the input and output characteristics of the pad. - * - * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength - * The Drive Strength configures the strength of the output driver on the - * pad. Normally, there is a fixed current limit that each I/O pin can safely - * drive, however some I/O pads offer a higher drive mode which increases this - * limit for that I/O pin at the expense of an increased power consumption. - * - * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate - * The Slew Rate configures the slew rate of the output driver, limiting the - * rate at which the pad output voltage can change with time. - * - * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode - * The Input Sample Mode configures the input sampler buffer of the pad. By - * default, the input buffer is only sampled "on-demand", i.e. when the user - * application attempts to read from the input buffer. This mode is the most - * power efficient, but increases the latency of the input sample by two clock - * cycles of the port clock.
