RADIO shorts tradeoffs

[blasagna]

Is there any downside to enabling all of the radio "shortcuts" controlled by the SHORTS radio register to avoid and reduce delays in the transmit and/or receive sequences? Is there any tradeoff one or more of these shortcuts will lead to, specifically in an application that is consistently engaged in wireless communication?

Hi,

No, there is no downside. The SHORTS are much faster than waiting for an interrupt on the CPU to perform the same operations. In general, when you want to perform a task which can be done with a short, the short is faster, more power efficient, and doesn't occupy the CPU.

An additionally related topic I want to mention is that the PPI channels can often be used in a similar fashion when a SHORT is not available for some event->task operation you would like to perform.

Best regards,
