14.16 Global Control Register (0Fh)
14.17 Line Length Channel ID Register (10h)
BIT
NAME
Description
This register is the global control for the AWG Auto-Increment, Automatic AIS insertion,
encoding/decoding and the jitter attenuators location, FIFO length and corner frequency for
all eight channels. Register bits default to 00h after power-up or reset.
[7]
AWG Auto-
Increment
The AWG Auto-Increment bit indicates whether to auto-increment the AWG Phase Address
Register (17h) (See Section 14.24 on page 40) after each access. Thus, when this bit is set,
the phase samples address portion of the address register increments after each read or
write access. This bit must be set before any bit in the AWG Enable register is set, if this
function is required.
[6]
RAISEN
On LOS, this bit controls the automatic AIS insertion into all eight receiver paths.
0 = Disabled
1 = Enabled

LLID 2-0
The value written to these bits specify the LIU channel for which the Pulse Shape Configura-
tion Data (register 11h) applies. For example, writing a value of a binary 000 to the 3-LSBs
will select channel 0. The pulse shape configuration data for the channel specified in this reg-
ister are written or read through the Line Length Data Register (11h). Register bits default
to 00h after power-up or reset.
