@{
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.
