43xx user manual defines 8 programmable interrupt priority levels, while lpc43xx.h file defines

#define __NVIC_PRIO_BITS  4   /*!< Number of Bits used for Priority Levels */= 16 programmable interrupt priority levels

what are the exact interrupt priority levels are avaliable in 43xx?
Can we modify the __NVIC_PRIO_BITS constant to modify the programmable interrupt priority levels in the 4330 device?
