Debug of the GE864-QUAD V2 in Production
To test and debug the mounting of the GE864-QUAD V2, we
strongly recommend to foreseen test pads on the host PCB, in
order to check the connection between the GE864-QUAD V2 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:
Ball

SERVICE
Service pin shall be used to upgrade the
module from ASC1 (RX_TRACE, TX_TRACE). The
pin shall be tied low to enable the feature
only in case of a SW Update activity. It is
required, for debug purpose, to be connected
to a test pad on the final application.
