Bits in this register indicate which function block introduced an interrupt signal on the INT pin.
The PRTY bit indicates a pending parity error indication needs serving in the Backplane Parity Configuration and Status registers.
Reading this register does not clear the interrupt indication. To clear the interrupt indication on the INT pin, the corresponding interrupt status reg-
Line Loop back means that the transmit line interface data and clock (LTDn and LTCKn) are internal directly comes from the received line data
= 0: Line loop back is disabled.
= 1: Line loop back is enabled.
Digital Loop back means that the received line data and clock (LRDn and LRCKn) are internal directly comes from the transmit line data and
= 0: Digital loop back is disabled.
= 1: Digital loop back is enabled.
This bit controls whether mimic pattern is generated. The mimic pattern is a copy of the F-bit. The mimic pattern is generated in the 1st bit of each
= 0: Mimic pattern is not generated.
= 1: Mimic pattern is generated.
= 0: Normal transmission.
= 1: Force the data to be transmitted on the TLDn pin to be all ‘Zero’s.
