8.5 Local Loopback
When CCR4.6 is set to 1, the DS21Q58 is forced into local loopback (LLB) mode. In this loopback, data continues
to be transmitted as normal. Data being received at RTIP and RRING is replaced with the data being transmitted.
Data in this loopback passes through the jitter attenuator (
Figure 3-1
).

NAME
BIT
FUNCTION
Line Interface Reset.
Setting this bit from 0 to 1 initiates an internal reset
that affects the clock recovery state machine and jitter attenuator.
Normally this bit is only toggled on power-up. It must be cleared and set
again for a subsequent reset.
Receive Elastic Store Align.
Setting this bit from 0 to 1 may force the
receive elastic store’s write/read pointers to a minimum separation of half
a frame. No action is taken if the pointer separation is already greater
than or equal to half a frame. If pointer separation is less than half a
frame, the command is executed and data is disrupted. This bit should be
toggled after SYSCLK has been applied and is stable. It must be cleared
and set again for a subsequent align. See Section
18
for details.
Receive Elastic Store Reset.
Setting this bit from 0 to 1 forces the
receive elastic store to a depth of one frame. Receive data is lost during
the reset. The bit should be toggled after SYSCLK has been applied and
is stable. It must be cleared and set again for a subsequent reset. See
Section
18
for details.
Receive Channel Monitor Bit 4.
MSB of a channel decode that
determines which receive channel data appears in the RDS0M register.
See Section
10
for details.
