Interrupt Controller Modules

10.3.1
The IPRHn and IPRLn registers,
map for each interrupt request to indicate if there is an active request (1 = active request, 0 = no request)
for the given source. The state of the interrupt mask register does not affect the IPRn. The IPRn is cleared
by reset. The IPRn is a read-only register, so any attempted write to this register is ignored. Bit 0 is not
implemented and reads as a zero.
