I am using the SPI in order to send/receive information.
"srts_status" variable first contains the result of the IRQ pin value.
Based on this, it then uses semaphores to gain access to specific blocks of code, something like this:
It isn't an acronym I recognize. Possibly it is specific to the system you are using.
As it refers to GPIO I'm guessing this is an MCU rather than some programmable gate array, can you tell us which it is and what SPI peripheral(s) it is talking to please.
