Target Connector Type
- This is a standard 20 pin double row (two rows of 10 pins) connector (pin to pin spacing: 2.54mm/0.100").
- Examples with housing: Samtec HTST-110-01-L-D (through-hole); Samtec HTST-110-01-L-DV (surface mount).
- Examples without housing: Samtec TSW-110-23-L-D; Berg 67996-120H
Target Connector Placement
- If terminal strip without shroud is used, the spacing marked with "A" must be a minimum of 30.6mm/1.2".
- If you place the connector the way that the even numbered pins show to the edge of the PCB,
then the flat cable goes straight off the PCB.
Interface Standard
The Debug Cable supports different interface standards:
| 1 | JTAG | IEEE 1149.1 | alternate pin function: TMS, TCK |
| 3 | Compact JTAG | IEEE 1149.7 | alternate pin function: TMSC, TCKC |
| 2 | Serial Wire Debug | CoreSight ARM | alternate pin function: SWDIO, SWCLK |
The interface type and corresponding pin function can be selected in the debuggers GUI.
