7.7 Interrupt Information Registers
The Interrupt Information Registers (IIRs) provide an indication of which Status Registers (SR1 to SR4)
are generating an interrupt. When an interrupt occurs, the host can read IIR to quickly identify which of
the four status registers are causing the interrupt.

Bit 0: Status Register 1 (SR1)
0 = Status Register 1 interrupt not active.
1 = Status Register 1 interrupt active.
Bit 1: Status Register 2 (SR2)
0 = Status Register 2 interrupt not active.
1 = Status Register 2 interrupt active.
Bit 2: Status Register 3 (SR3)
0 = Status Register 3 interrupt not active.
1 = Status Register 3 interrupt active.
Bit 3: Status Register 4 (SR4)
0 = Status Register 4 interrupt not active.
1 = Status Register 4 interrupt active.
Bit 4: Status Register 5 (SR5)
0 = Status Register 5 interrupt not active.
1 = Status Register 5 interrupt active.
Bits 5 to 7: Unused
