All interrupt priorities higher than configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY must not call any FreeRTOS functions! Note that on Cortex ARM architectures higher priorities have lower value.

With an in-circuit-debugger, the read out on a TX16S with only internal module configured resulted in the following NVIC register readouts (all values as hex values):

Interrupt enable state (NVIC_ISER) from 0xE000E100:
