Description
The alt_irq_enable_all() function enables all interrupts that were previously disabled by
alt_irq_disable_all(). The input argument, context, is the value returned by a previous call to
alt_irq_disable_all(). Using context allows nested calls to alt_irq_disable_all() and
alt_irq_enable_all(). As a result, alt_irq_enable_all() does not necessarily enable all interrupts,
such as interrupts explicitly disabled by alt_irq_disable().
