LIU Line Interface Reset n
Bit 15 is LIRST8; bit 8 is LIRST1. A zero-to-one transition resets
the receiver’s clock recovery state machine and re-centers the
jitter attenuator (JA) FIFO pointers for the corresponding LIU. This
is an asynchronous reset. See section
10.5.0 = Normal operation
1 = Reset receiver and JA of LIU n

LIU Software Reset n
Bit 7 is LSRST8; bit 0 is LSRST1. A zero-to-one transition resets
LIU logic and registers for the corresponding LIU. The reset is
released when a zero is written to this bit. See section
10.5.0 = Normal Operation
1 = Reset LIU n

TDM-over-Packet Interrupt Status
This status bit indicates when the TDM-over-Packet block is
signaling an interrupt request. This bit is typically used when
H_INT[0] and H_INT[1] are ORed together (i.e. when
0 = TDM-over-Packet has not issued an interrupt.
1 = TDM-over-Packet has issued an interrupt.

LIU Interrupt Status n
Bit 23 is LIS8; bit 16 is LIS1. LISn reports the interrupt status for
LIU n. Each LISn bit is only cleared when the
LLSR register is
cleared for the corresponding LIU. Interrupt mask is
GTIMR.LIMn.0 = LIU n has not issued an interrupt.
1 = LIU n has issued an interrupt.

BISn
RO
0
BERT Interrupt Status n
Bit 15 is BIS8; bit 8 is BIS1. BISn reports the interrupt status for
BERT n. Each BISn bit is only cleared when the
BSRL register is
cleared for the corresponding BERT. Interrupt mask is
0 = BERT n has not issued an interrupt.
1 = BERT n has issued an interrupt.
[7:0]
FISn
RO
0
Framer Interrupt Status n
Bit 7 is FIS8; bit 0 is FIS1. FISn reports the interrupt status for
framer n. Each FISn bit is only cleared when the latched status
register causing the interrupt is cleared for the corresponding
framer. Interrupt mask is
GTIMR.FIMn.
0 = Framer n has not issued an interrupt.
1 = Framer n has issued an interrupt.
