UMTS/HSPA UC20 EVB User Guide 4.3. Reset The emergency restart option is only used in the case of emergency. In this situation, due to serious problem, the software is not responding for more than 5 seconds. Pulling down the module’s RESET_N pin by pressing the key S203 (more than 100ms) causes at release a reset of UC20 Module. This may cause the loss of information stored in the memory since the reset is initialized. l e t l c a e i t u n Q ide f n o C 4.4. Communication via USB or Serial Port 1. 2.
