Expand description

@brief Checks if the current core is in an ISR context

  • ISR context consist of Low/Mid priority ISR, or time tick ISR
  • High priority ISRs aren’t detected here, but they normally cannot call C code, so that should not be an issue anyway.

@note [refactor-todo] Check if this should be inlined @return

  • pdTRUE if in ISR
  • pdFALSE otherwise
