These bits defines the length of the user-programmable LLB
deactivate code, which is programmable in register LCR2.
00 = 5 bit
01 = 6 bit (default)
10 = 7 bit
11 = 8 bit
If a shorter pattern length is required, select a multiple of the required
length and repeat the pattern in LCR2.

Normal operation (default)
Normal data is replaced by the LLB deactivation code
continuously until this bit is reset.
LCR1.XLA and LIM3.XPRBS must be cleared. LLB deactivate
code can be inserted in receive (LIM3.GTP = 0) or transmit
direction (LIM3.GTP = 1).
