sid_pal_enter_critical_region#

void sid_pal_enter_critical_region ()

Code executed between calls of function declared below will be protected from interruption from different thread or ISR context.

Note

  • Implementation is actually disabled IRQ's, so remember, amount of code and execution time of code between calls of enter and exit functions should be as minimal as possible

Implements disabling of all hardware and software interrupts
