7.6 Information Registers
Information registers operate the same as status registers except they cannot cause interrupts. INFO3
register is a read-only register and it reports the status of the E1 synchronizer in real time. INFO3
information bits are not latched, and it is not necessary to precede a read of these bits with a write.
7.7 Interrupt Information Registers
The Interrupt Information Registers provide an indication of which Status Registers (SR1 through SR4)
are generating an interrupt. When an interrupt occurs, the host can read IIR to quickly identify which of
the three 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 1 interrupt not active.
1 = Status Register 1 interrupt active.
Bit 2: Status Register 3 (SR3)
0 = Status Register 1 interrupt not active.
1 = Status Register 1 interrupt active.
Bit 3: Status Register 4 (SR4)
0 = Status Register 1 interrupt not active.
1 = Status Register 1 interrupt active.
Bits 4 to 7: Unused
