Thirty-two Local Output Advancement Registers (LOAR0 to LOAR31) allow users to program the output
advancement for output data streams LSTo0 to LSTo31. The possible adjustment is -2 (15ns), -4 (31ns) or -6 (46ns)
cycles of the internal system clock (131.072MHz).
The LOAR0 to LOAR31 registers are configured as follows:
13.5.1
The binary value of these two bits indicates the amount of offset that a particular stream output can be advanced
with respect to the output frame boundary. When the advancement is 0, the serial output stream has the normal
alignment with the generated frame pulse FP8o.
(where n = 0 to 31)
