Register Descriptions

13.2.1.1 Interrupt Pending Registers (IPRH, IPRL)

The IPRH and IPRL registers,
for each interrupt request to indicate if there is an active request for the given source (1 = active request,
0 = no request). The state of the interrupt mask register does not affect the IPR. The IPR is cleared by reset.
