interrupt source or sources are signalling the interrupt. Second, it serves as the method to clear
the interrupt reporting.

Description
Reserved bits return an indeterminate value, and should
never be changed.
Programming Masked Interrupt Status and Clear
This bit indicates whether an interrupt was signaled
because a programming cycle completed and was not
masked. This bit is cleared by writing a 1. The PRIS bit in
the FCRIS register (see page 102) is also cleared when the
PMISC bit is cleared.
Access Masked Interrupt Status and Clear
This bit indicates whether an interrupt was signaled
because an improper access was attempted and was not
masked. This bit is cleared by writing a 1. The ARIS bit in
the FCRIS register is also cleared when the AMISC bit is
cleared.
