Number of K24 interrupt priorities?

I'm chasing down what appears to be screwball interrupt responses. Section of the K24 reference manual states the chip has 16 interrupt priority levels. The MQX PSP cortex.h header states  "#define CORTEX_PRIOR_IMPL  (3) " which is manipulated into a left-justified 3-bit mask as required for the NVIC.

- Does the chip have 8 or 16 levels?

- If 16, is the use of 8 by MQX intentional?
