CHAPTER 5 INTERRUPTS
5.1 Interrupts
5.1.1 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.
■ Register Configuration
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.
