This register controls the delay from the APSIFP input signal to the time when the S/UNI-2488
may safely process the J0 characters delivered by the APS Input serial data links (APSI+/-[4:1]).
AIJ0DLY[13:0]:
The APS Input transport frame delay bits (AIJ0FP[13:0]) controls the delay, in REFCLK
cycles, inserted by the S/UNI-2488 before processing the J0 characters delivered by the APS
Input serial data links (APSI+/-[4:1]). AIJ0DLY is set such that after the specified delay, all
active APS Input links would have delivered the J0 character. The relationships of AIJ0FP,
AIJ0DLY[13:0] and the system configuration are described in the Functional Timing section.
Valid values of AIJ0DLY[13:0] are 0000H to 25F7H.
