How to Enable BusFault, MemManage Interrupts

Hi,

Is it neccessary to do something to enable BusFault and MemManage Interrupts, or are these active as per default?

I.e. the HardFault interrupt is always enabled, the only thing I need to do is add a HardFault_Handler
But is the same true for BusFault? Or Do I need to do a NVIC_Init for BusFault_IRQn, UsageFault_IRQn etc.

The UsageFault_IRQn has a definition of -10, which looks not to be suitable for the "NVIC_Init" function.

The documentation does specify UsageFault_IRQn and BusFault to be settable priority, so perhaps this indicated that they are not always enabled and should be done so by user code?
