mbed_official 579:53297373a894 84 *
mbed_official 579:53297373a894 85 * The SAM devices contain a number of General Purpose I/O pins, used to
mbed_official 579:53297373a894 86 * interface the user application logic and internal hardware peripherals to
mbed_official 579:53297373a894 87 * an external system. The Pin Multiplexer (PINMUX) driver provides a method
mbed_official 579:53297373a894 88 * of configuring the individual pin peripheral multiplexers to select
mbed_official 579:53297373a894 89 * alternate pin functions.

mbed_official 579:53297373a894 103 * selected device supports those features.
mbed_official 579:53297373a894 104 *
mbed_official 579:53297373a894 105 * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins
mbed_official 579:53297373a894 106 * SAM devices use two naming conventions for the I/O pins in the device; one
mbed_official 579:53297373a894 107 * physical and one logical. Each physical pin on a device package is assigned
mbed_official 579:53297373a894 108 * both a physical port and pin identifier (e.g. "PORTA.0") as well as a
mbed_official 579:53297373a894 109 * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the
mbed_official 579:53297373a894 110 * former is used to map physical pins to their physical internal device module
mbed_official 579:53297373a894 111 * counterparts, for simplicity the design of this driver uses the logical GPIO
mbed_official 579:53297373a894 112 * numbers instead.
mbed_official 579:53297373a894 113 *
mbed_official 579:53297373a894 114 * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing
mbed_official 579:53297373a894 115 * SAM devices contain a peripheral MUX, which is individually controllable
mbed_official 579:53297373a894 116 * for each I/O pin of the device. The peripheral MUX allows you to select the
mbed_official 579:53297373a894 117 * function of a physical package pin - whether it will be controlled as a user
mbed_official 579:53297373a894 118 * controllable GPIO pin, or whether it will be connected internally to one of
mbed_official 579:53297373a894 119 * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is
mbed_official 579:53297373a894 120 * configured in GPIO mode, other peripherals connected to the same pin will be
mbed_official 579:53297373a894 121 * disabled.
mbed_official 579:53297373a894 122 *
mbed_official 579:53297373a894 123 * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics
mbed_official 579:53297373a894 124 * There are several special modes that can be selected on one or more I/O pins
mbed_official 579:53297373a894 125 * of the device, which alter the input and output characteristics of the pad.
mbed_official 579:53297373a894 126 *
mbed_official 579:53297373a894 127 * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength
mbed_official 579:53297373a894 128 * The Drive Strength configures the strength of the output driver on the
mbed_official 579:53297373a894 129 * pad. Normally, there is a fixed current limit that each I/O pin can safely
mbed_official 579:53297373a894 130 * drive, however some I/O pads offer a higher drive mode which increases this
mbed_official 579:53297373a894 131 * limit for that I/O pin at the expense of an increased power consumption.
mbed_official 579:53297373a894 132 *
mbed_official 579:53297373a894 133 * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate
mbed_official 579:53297373a894 134 * The Slew Rate configures the slew rate of the output driver, limiting the
mbed_official 579:53297373a894 135 * rate at which the pad output voltage can change with time.
mbed_official 579:53297373a894 136 *
mbed_official 579:53297373a894 137 * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode
mbed_official 579:53297373a894 138 * The Input Sample Mode configures the input sampler buffer of the pad. By
mbed_official 579:53297373a894 139 * default, the input buffer is only sampled "on-demand", i.e. when the user
mbed_official 579:53297373a894 140 * application attempts to read from the input buffer. This mode is the most
mbed_official 579:53297373a894 141 * power efficient, but increases the latency of the input sample by two clock
mbed_official 579:53297373a894 142 * cycles of the port clock. To reduce latency, the input sampler can instead
mbed_official 579:53297373a894 143 * be configured to always sample the input buffer on each port clock cycle, at
mbed_official 579:53297373a894 144 * the expense of an increased power consumption.
mbed_official 579:53297373a894 145 *
