The GLISR1 register reports the LIU interrupt status for the T1/E1 LIUs of Channels 1 to 4. A logic one in the
associated bit location indicates a LIU has set its interrupt signal.
Bit 3: LIU Interrupt Status 4 (LIS4)
0 = LIU 4 has not issued an interrupt.
1 = LIU 4 has issued an interrupt.
Bit 2: LIU Interrupt Status 3 (LIS3)
0 = LIU 3 has not issued an interrupt.
1 = LIU 3 has issued an interrupt.
Bit 1: LIU Interrupt Status 2 (LIS2)
0 = LIU 2 has not issued an interrupt.
1 = LIU 2 has issued an interrupt.
Bit 0: LIU Interrupt Status 1 (LIS1)
0 = LIU 1 has not issued an interrupt.
1 = LIU 1 has issued an interrupt.

The GLISR register reports the HDLC-256 interrupt status for Channels 1 through 8. A logic one in the associated
bit location indicates a HDLC-256 has set its interrupt signal.
Bit 3 : HDLC-256 Interrupt Status 4
0 = HDLC-256 4 has not issued an interrupt.
1 = HDLC-256 4 has issued an interrupt.
Bit 2 : HDLC-256 Interrupt Status 3
0 = HDLC-256 3 has not issued an interrupt.
1 = HDLC-256 3 has issued an interrupt.
Bit 1 : HDLC-256 Interrupt Status 2
0 = HDLC-256 2 has not issued an interrupt.
1 = HDLC-256 2 has issued an interrupt.
Bit 0 : HDLC-256 Interrupt Status 1
0 = HDLC-256 1 has not issued an interrupt.
1 = HDLC-256 1 has issued an interrupt.
