| LA-4530 | uTrace for Cortex-M | (obsolete) |
Target Connector Type
The µTrace can be used with three different connectors (10-pin, 20-pin, 34-pin).
Interface Standard
The µTrace supports different interface standards:
| JTAG | IEEE 1149.1 | alternate pin function: TMS, TCK, TDO |
| Serial Wire Debug | CoreSight ARM | alternate pin function: SWDIO, SWCLK, SWO |
The interface type and corresponding pin function can be selected in the debuggers GUI.
Pinout
 10-pin MIPI connector (debug only; optional: serial wire output)
The alternate signals TMSC and TCKC (cJTAG) are not supported.
