CRITICAL_SECTION

#define CRITICAL_SECTION    if (auto cs = sbl::core::patterns::synchronization::CriticalSection(); true)

Convenience macro for ARM critical sections.

Creates an ARM critical section with automatic variable naming. Simplified for ARM-only usage without controller parameter.

Usage:

CRITICAL_SECTION {
    // Protected code here - ARM interrupts disabled
    shared_data++;
} // Automatically restored
