This register controls the delay from the APSIFP input signal to the time when the S/UNI-2488
produces the J0 pulse on the APS Output serial data links (APSO+/-[4:1]).
AOJ0REFDLY[13:0]:
The APS Output transport frame delay bits (AOJ0REFDLY [13:0]) control the delay, in
REFCLK cycles, inserted by the S/UNI-2488 between receiving a reference J0 frame pulse
on APSIFP, and presenting the outgoing J0 character on APSO+/-[4:1]. The relationships of
APSIFP, AOJ0REFDLY [13:0] and the system configuration are described in the Functional
Timing section.
Valid values of AOJ0REFDLY [13:0] are 0000H to 25F7H.
