taskDISABLE_INTERRUPTS to disable *all* maskable initerrupts?

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 taskDISABLEINTERRUPTS taskDISABLEINTERRUPTS * ingroup SchedulerControl */

define taskDISABLEINTERRUPTS() portDISABLEINTERRUPTS()

~~~ And in the ARM_CM4F port it is implemeted as: #define portDISABLE_INTERRUPTS() vPortRaiseBASEPRI() Which only masks interrupts up to configMAXSYSCALLINTERRUPT_PRIORITY. I understand that taskENTERCRITICAL() would mask up to configMAXSYSCALLINTERRUPTPRIORITY, but according to the description taskDISABLEINTERRUPTS should maks *all* interrupts (and not only up to configMAXSYSCALLINTERRUPTPRIORITY)? Thanks, Erich

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