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.
Connector P1
It exposes DAP and AGBT interface.
