DAP Hardware I/O Pin Access Functions

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.

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.
