SI4468-7 Datasheet, PDF (47/57 Pages) Silicon Laboratories – Highly configurable packet handler

Si4468/7
10. Packet Trace Port
The device integrates a true PHY-level Packet Trace Interface (PTI) for effective network-level debugging. PTI
monitors all the PHY Tx and Rx packets without affecting their normal operation. This asynchronous interface
provides a trace of all over-the-air packet data as well as packet status via a single user-selectable GPIO. PTI can
be disabled in software and cannot be used to inject packets into the modem interface. The default baud rate of the
PTI interface is 500 kbaud, which is optimal to support a 250 kbps data rate. PTI is supported on Si4468/7 in the
15.4 boot mode only and is supported by Silicon Labs Development tools.
