12.3.3. Debug of the UC864-E/G/WD/WDU in Production
To test and debug the mounting of UC864-E/G/WD/WDU, we strongly recommend to
foresee test pads on the host PCB, in order to check the connection between the
UC864-E/G/WD/WDU itself and the application and to test the performance of the
module connecting it with an external computer. Depending on the customer
application, these pads include, but are not limited to the following signals:
• TXD
• RXD
• ON/OFF
• RESET
• GND
• VBATT
• TX_TRACE
• RX_TRACE
• PWRMON
