Preliminary Information
13.8
Address 0083h to 0092h.
Sixteen Local output advancement registers (LOAR0 to LOAR15) allow users to program the output
advancement for output data streams LSTo0 to LSTo15. The possible adjustment is -2, -4 or -6 cycles of the
internal system clock (131.072MHz).
The LOAR0 to LOAR15 registers are configured as follows:
13.8.1
The binary value of these two bits is the amount of offset that a particular stream output can be advanced.
When the advancement is 0, the serial output stream has the normal alignment with the Local frame pulse.
(where n = 0 to 15)
