The Long-Term Evolution (LTE) modem trace interface enables logging of LTE modem behavior.
Customer must provide support for application software to activate LTE modem tracing. Trace data can be received through a customer-selected protocol or bus, such as a UART bus with two I/O pins (RX and TX). Customer can choose which General-Purpose Input/Output (GPIO)s (P0.00 to P0.31) to use for this purpose, however pins P0.21–P0.25 are recommended to be reserved for ETM and ITM trace interface.
