Operation

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 target. 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.
P1 Connector
It exposes DAP and AGBT interface.
