To debug the F280025C, ensure that
the jumpers on J101 are connected to
pass the TMS and TCK signals to the
MCU. RXD and TXD are optional.
These are for Channel B of the
Debugger to enable a serial interface
to the connected PC.
If debugging an external target ,
remove the jumpers from J101 and
connect the external target to J102.
