IPR Registers
The Interrupt Priority (IPR) registers contain the individ-
ual priority bits for the peripheral interrupts. Due to the
number of peripheral interrupt sources, there are three
Peripheral Interrupt Priority registers (IPR1, IPR2 and
IPR3). The operation of the priority bits requires that
the Interrupt Priority Enable bit (IPEN) be set.

IPR1: PERIPHERAL INTERRUPT PRIORITY REGISTER 1

Note 1: This bit is only available on PIC18F4X8 devices. For PIC18F2X8 devices, this bit
is unimplemented and reads as ‘0’.
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
