CC1310: Latency wakeup time cc1310 main cpu

Vitaly Peimer

Part Number: CC1310

Hello,

I'm waking up the main cpu cc1310 from standby mode. The latency is 340 us.

According the documents it's need to be ~174 us and ~14 us for TIRTOS. Total of  ~190 us.

What am I missing?

Test scenario:

sleep -> receive GPIO interrupt -> wakeup -> set different GPIO to HIGH.

*Measures are done by scope

BR,

Vitaly

    How are you benchmarking this? Note that the numbers specified in the documents you have read (if you could say which documents that would help) are probably measured from standby to first instruction running on the CPU. This does not translate to first instruction running in main().
