Description
LOAn1-0
(See Note 1)
Local Output Advancement Bits 1-0:
These two bits represent the amount of offset
that a particular stream output can be advanced. When the offset is zero, the serial
output stream has normal alignment with the frame pulse.
Note 1: n denotes a LSTo stream number from 0 to 15.
