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
---------------------------- | -------------------- | ---------------------------------------------
TCK: Test Clock              | SWCLK: Clock         | Output Push/Pull
TMS: Test Mode Select        | SWDIO: Data I/O      | Output Push/Pull; Input (for receiving data)
TDI: Test Data Input         |                      | Output Push/Pull
TDO: Test Data Output        |                      | Input             
nTRST: Test Reset (optional) |                      | Output Open Drain with pull-up resistor
nRESET: Device Reset         | nRESET: Device Reset | Output Open Drain with pull-up resistor


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.
