Jumper J2
The jumper J2 is optional and by default not populated. It connects 10k pull-down resistor to
the USERIO pin when bridged.
The jumper has been introduced for a custom target, where the target watchdog gets disabled
during the debugging, when low level at the USERIO signal (target debug connector pin 7) is
detected.
The debug adapter connects to the target via a 10-pin 1.27mm connector, Samtec SFM-105-01-
S-D). A target should feature a matching part, for example Samtec TFM-105-01-L-D.
This adapter is used only in conjunction with the 14-pin 2.54mm MPC5xxx Debug
Adapter (ordering code IC50150) and optionally with the 16-pin 2.54mm Infineon JTAG
Debug Adapter (ordering code IC50160).
