2016-08-28 · While FreeRTOS makes every effort to keep such critical sections as small and fast as possible, they are certainly longer than a few CPU instructions. The good news is that for the Cortex-M3/M4/M7 ports, not all interrupts are disabled: FreeRTOS is taking advantage of the BASEPRI register (see Part 1). They are behind yet another macro as below:

The interrupt latency of the Cortex-M series processor is quite low and is deterministic. For example, the Cortex-M3 and Cortex-M4 processors have an interrupt latency of only 12 clock cycles. This latency includes time required to push a number of registers to the stack, which allows an ISR to be written as a normal C function, and avoid any hidden software overhead in interrupt processing.

My understanding is interrupt is disabled for brief period to save the CPSR_IRQ to SPSR_SYS and also save the system mode registers before handling the new interrupt. Correct me If I am wrong. Sorry for deviating from CORTEX-M to CORTEX-A, I am just curious about how interrupt is handled in ARM.

However, I want to answer it in another way, maybe you find it helpful. The LPC11xx (Cortex-M0) has 4 levels for GPIO pins, all the pins from GPIO0.0 to GPIO0.n share the same interrupt number, and all the pins from GPIO3.0 to GPIO3.m share the same interrupt number. The Cortex-M series processors include an interrupt controller called the Nested Vector Interrupt Controller for interrupt handling such as interrupt prioritisation and interrupt masking. The NVIC contains a number of programmable registers for interrupt management such as enable/disable, and priority levels.
