Configuration
J1: Target reset configuration
Jumper J1 connects the Emulation Adapter reset line and the user target board reset line and
is populated by default.
J2: TP20_2/TESTMODEn configuration
The TP20_2/TESTMODEn microcontroller pin is latched at power on reset release to enter test
mode. Alternatively, it can operate as a general purpose I/O.
The Solder jumper J2 connects the Emulation Adapter TP20_2/TESTMODEn signal with the
microcontroller TP20_2 signal from the user target board. The microcontroller must not enter
test mode during the Emulation Adapter operation. The J2 jumper is by default not connected
preventing the microcontroller on the Emulation Adapter entering test mode at power on reset
if the target would be set up so. If the target uses this pin for I/O operation, solder the jumper
J2 and double check that the signal is properly conditioned at power on reset.
