BYTEsel
LCV Counter Byte Select
This bit is used to select the MSB or LSB for Reading the contents
of the LCV counter for a given channel. The channel is addressed
by using bits D[3:0] in register 0x8Ch. By default, the LSB byte is
selected.
0 = Low Byte
1 = High Byte

D1
chUPDATE LCV Counter Update Per Channel
This bit is used to latch the contents of the counter for a given
channel into a holding register so that the value of the counter can
be read. The channel is addressed by using bits D[3:0] in register
0x8Ch.
0 = Normal Operation
1 = Updates the Selected Channel

chRESET
LCV Counter Reset Per Channel
This bit is used to reset the LCV counter of a given channel to its
default state 0000h. The channel is addressed by using bits D[3:0]
in register 0x8Ch. This bit must be set to "1" for 1
S.
0 = Normal Operation
1 = Resets the Selected Channel

Line Code Violation Byte Contents
These bits contain the LCV counter contents of the Byte selected
by bit D2 in register 0x8Dh for a given channel. The channel is
addressed by using bits D[3:0] in register 0x8Ch. By default, the
contents contain the LSB, however no channel is selected..
