11.9.1 Debug of the UC864-E in production

To test and debug the mounting of the UC864-E, we strongly recommend to foreseen test pads on the host PCB, in order to check the connection between the UC864-E itself and the application and to test the performance of the module connecting it with an external computer.

Depending by 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
