6. Can I power the kit using external program/debug headers J11 and J12?
No, this is not possible by default in this board. The target MCU is powered by on-board
regulators only and hence one of the 3 main sources (
J5
,
J6
and
J7
) must be present.
There is a protection circuit that prevents reverse voltage from VTARG_REF to VTARG. Hence
the board can't be powered through
J11
and
J12
. However this can be by-passed by loading
R130.
Note:
This modification is not recommended as the target MCU will have no protection and will
be permanently damaged if 5V is supplied.

Note: VTARG_REF is only output voltage sense line
for external debuggers. PSoC 6 can't be powered
using external debugging headers J11 and J12

Note: If R130 is loaded and external power is used,
make sure to remove jumper shunt from J14 to
prevent reverse voltage to on-board regulator
