behavior/arrangement of mcliccfg.nlbits/scliccfg.nlbits/ucliccfg.nlbits #311

separating additional question raised in issue #304 into a new issue: Additionally, can you please clarify the behavior of the xcliccfg.nlbits fields; specifically:

Are xcliccfg.nlbits fields independent of each other, or are they aliases of the same thing? and: If xcliccfg.nlbits fields are independent, is it the case that mcliccfg.nlbits is used to determine the level of interrupts targeting M-mode, scliccfg.nlbits is used to determine the level of interrupts targeting S-mode and ucliccfg.nlbits is used to determine the level of interrupts targeting U-mode? Thanks.
