+

Control and monitor SWD/JTAG Pins.

+

The DAP_SWJ_Pins Command is used to monitor and control the I/O Pins including the nRESET Device reset line.

+

The Pin Wait time is useful in systems where the nRESET pin is implemented as open-drain output. After nRESET is de-asserted by the debugger, external circuit may still hold the target Device under reset for a time. Using the Pin Wait time, the debugger may monitor selected I/O Pins and wait until they the expected value appears or a timeout expires.

+

I/O Pin Mapping for the fields Pin Output, Pin Select, and Pin Input:

+
    +
  • Bit 0: SWCLK/TCK
    • +
  • Bit 1: SWDIO/TMS
    • +
  • Bit 2: TDI
    • +
  • Bit 3: TDO
    • +
  • Bit 5: nTRST
    • +
  • Bit 7: nRESET
    • +
+

DAP_SWJ_Pins Command:

+
| BYTE | BYTE ******| BYTE ******| Word ****|
+
> 0x10 | Pin Output | Pin Select | Pin Wait |
+
|******|************|************|**********|
+
    +
  • Pin Output: Value for selected output pins
    • +
  • Pin Select: Selects which output pins will be modified
    • +
  • Pin Wait: Wait timeout for the selected output to stabilize
      +
    • 0 = no wait
      • +
    • 1 .. 3000000 = time in µs (max 3s)
      • +
    +
    • +
+

DAP_SWJ_Pins Response:

+
| BYTE | BYTE *****|
+
< 0x10 | Pin Input |
+
|******|***********|
+
    +
  • Pin Input: Pin state read from target Device.
