Interrupt Level Setting Registers (ILR0 to ILR5)

The interrupt level setting registers (ILR0 to ILR5) contain 24 pairs of 2-bit data
assigned to the interrupt requests of different peripheral functions. Each pair
of bits (interrupt level setting bits) is used to set the interrupt level of an
interrupt request.

ILR1
bit 7
Field L07[1:0]
Attribute R/W

ILR2
bit 7
Field L11[1:0]
Attribute R/W
Initial value 1
ILR3
bit 7
Field L15[1:0]
Attribute R/W
Initial value 1
ILR4
bit 7
Field L19[1:0]
Attribute R/W
Initial value 1
ILR5
bit 7
Field L23[1:0]
Attribute R/W
Initial value 1
The interrupt level setting registers assign a pair of bits to every interrupt request. The values
of interrupt level setting bits in these registers represent the priority of an interrupt request
(interrupt level: 0 to 3) in interrupt processing.
