Target Connector Placement

The adaption uses one or two 38 pin Mictor connectors.
The second connector is only needed if the target trace port provides more than 16 trace data pins and for 8/16 bit demuxed mode.
A separation distance of 1350 mil is required if adaption without flex cable is intended.
We recommend to place the even numbered pins at the PCB border side (flex cable won't be twisted).

Debug Signals

The pinout of the Mictor connector optionally includes the debug signals which needs to go to the Debug Cable
(20-pin standard header). The Preprocessors have a 20-pin connector where the user can plug in the Debug Cable.
Alternatively the Debug Cable can be plugged on a separate 20-pin connector on the target. In this case there is no
need to connect the debug signals to the Mictor. For better signal quality it is better not to connect them.
The debug signals are DBGRQ, RESET-, TDO, RTCK, TCK, TMS, TDI, TRST- DBGACK, VREF-DEBUG.
