Jitter Attenuator RESET - Channel_n:
Writing a "0 to 1" transition within this bit-field will configure the Jitter
Attenuator (within Channel_n) to execute a RESET operation.
Whenever the user executes a RESET operation, then following will
occur.
The READ and WRITE pointers (within the Jitter Attenuator FIFO)
will be reset to their default values.
The contents of the Jitter Attenuator FIFO will be flushed.
N
OTE
:
The user must follow up any "0 to 1" transition with the
appropriate write operate to set this bit-field back to "0", in
order to resume normal operation with the Jitter Attenuator.

Jitter Attenuator Configuration Select Input - Bit 1:
This READ/WRITE bit-field, along with Bit 0 (JA0 Ch_n) is used to do
any of the following.
To enable or disable the Jitter Attenuator corresponding to
Channel_n.
To select the FIFO Depth for the Jitter Attenuator within Channel_n.
The relationship between the settings of these two bit-fields and the
Enable/Disable States, and FIFO Depths is presented below.
