0
Bits 7 to 0: Individual Jitter Attenuator Enable Channel n (IJAEn).
When this bit is set, the LIUn jitter attenuator
is enabled. Note that if the GC.JAE bit is set, this register is ignored.

Default
0
Bits 7 to 0: Individual Jitter Attenuator Position Select Channel n (IJAPSn).
When this bit is set , the jitter
attenuator is in the receive path of LIUn, and when this bit is reset the jitter attenuator is in the transmit path of
LIUn. Note that if the GC.JAE bit is set, this register is ignored.

Default
0
Bits 7 to 0: Individual Jitter Attenuator FIFO Depth Select n (IJAFDSn).
When this bit is set for LIUn, the jitter
attenuator FIFO depth is 128 bits. When reset, the jitter attenuator FIFO depth is 32 bits. Note that if the
GC.IJAFDS bit is set, this register is ignored.

0
Bits 7 to 0: Individual Jitter Attenuator FIFO Limit Trip n (IJAFLTn).
Set when the jitter attenuator FIFO
reaches to within 4 bits of its useful limit for the transmitter of LIUn. This bit is cleared when read if GISC.CWE is
reset. This bit is cleared by a write operation to the bit if GISC.CWE is set.
