+Standard I/O Pins of the CMSIS-DAP Hardware Debug Port support standard JTAG mode
+and Serial Wire Debug (SWD) mode. In SWD mode only 2 pins are required to implement the debug
+interface of a device. The following I/O Pins are provided:
+
+JTAG I/O Pin                 | SWD I/O Pin          | CMSIS-DAP Hardware pin mode

+DAP Hardware I/O Pin Access Functions
+-------------------------------------
+The various I/O Pins are accessed by functions that implement the Read, Write, Set, or Clear to
+these I/O Pins.
+
+For the SWDIO I/O Pin there are additional functions that are called in SWD I/O mode only.
+This functions are provided to achieve faster I/O that is possible with some advanced GPIO
+peripherals that can independently write/read a single I/O pin without affecting any other pins
+of the same I/O port. The following SWDIO I/O Pin functions are provided:
+ - \ref PIN_SWDIO_OUT_ENABLE to enable the output mode from the DAP hardware.
+ - \ref PIN_SWDIO_OUT_DISABLE to enable the input mode to the DAP hardware.
+ - \ref PIN_SWDIO_IN to read from the SWDIO I/O pin with utmost possible speed.
+ - \ref PIN_SWDIO_OUT to write to the SWDIO I/O pin with utmost possible speed.
