1. - Setting interrupt priority use the register of NT_CFDATA0–7->PRIOLVL[2:0] , you can find the detail inforamtion in page 177 of <MC9S12ZVM-Family Reference Manual and Datasheet>, and Table 4-7 Interrupt Priority Levels . - About the theory, please take a look at description of...
there are not 0-192 priority levels. The ARM core would allow up to 127 *preemption* levels with up to 256 (8bit) interrupt values. I recommend to have a read at https://mcuoneclipse.com/2016/08/14/arm-cortex-m-interrupts-and-freertos-part-1/, especially the section about the shif...
