I’m trying to write a program for a MSP430 and in my design it is important that one TimerB interrupt is not allowed to disable because it is very time critical and this interrupt can appear in some 10-20µs.
In the freeRTOS I found that global interrupt disable is used (portDISABLE_INTERRUPTS()).
Is there something to keep in mind to change this that all interrupt except the Timer B interrupt?
This interrupt routine will save all changed registers.
Is freeRTOS still executable when one interrupt can appear all the time?
