E1 Arbitrary Pulse Enable
This bit is used to enable the Arbitrary Pulse Generators for shap-
ing the transmit pulse shape when E1 mode is selected. If this bit
is set to "1", all 14 channels will be configured for the Arbitrary
Mode. However, each channel is individually controlled by pro-
gramming the channel registers 0xn8 through 0xnF, where n is the
number of the channel.
"0" = Disabled (Normal E1 Pulse Shape ITU G.703)
"1" = Arbitrary Pulse Enabled

Device "ID" The device "ID" of the XRT83VSH314 short haul LIU is 0xF2h.
Along with the revision "ID", the device "ID" is used to enable soft-
ware to identify the silicon adding flexibility for system control and
debug.

Revision
"ID"
The revision "ID" of the XRT83VSH314 LIU is used to enable soft-
ware to identify which revision of silicon is currently being tested.
The revision "ID" for the first revision of silicon will be 0x01h.
NOTE: The value contained in this register is subject to change
when a newer revision of the silicon has been issued.
