Hello,

On http://www.freertos.org/a00020.html#taskDISABLE_INTERRUPTS it says:

*taskDISABLEINTERRUPTS
task. h

Macro to disable all maskable interrupts.

This macro should rarely be called directly. Use taskENTERCRITICAL() and taskEXITCRITICAL() instead.
**

But checking Cortex-M4 ports, it only disable interrupts up to

/**
 * task. h
 *
 * Macro to disable all maskable interrupts.
 *
 * \defgroup taskDISABLE_INTERRUPTS taskDISABLE_INTERRUPTS
 * \ingroup SchedulerControl
 */
#define taskDISABLE_INTERRUPTS()	portDISABLE_INTERRUPTS()

And in the ARM_CM4F port it is implemeted as:
#define portDISABLE_INTERRUPTS() vPortRaiseBASEPRI()

Which only masks interrupts up to configMAX_SYSCALL_INTERRUPT_PRIORITY.

I understand that taskENTER_CRITICAL() would mask up to configMAX_SYSCALL_INTERRUPT_PRIORITY, but according to the description taskDISABLE_INTERRUPTS should maks all interrupts (and not only up to configMAX_SYSCALL_INTERRUPT_PRIORITY)?

Thanks,
Erich

You are right - I think this is a case of very old documentation, which I will correct. Thanks for the heads-up.
