Address 0083h to 00A2h.
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, -4 or -6 cycles of the internal system clock
(131.072 MHz).
The LOAR0 to LOAR31 registers are configured as follows:
