Transmit Offset
Initial value loaded into the transmit bit counter at the trigger edge of
SCLKX when the synchronous pulse on port SYPX/XMFS is active
Refer to register XC1.
A write access to this address resets the transmit elastic buffer to its
basic starting position. Therefore, updating the value should only be
done when the FALC
centered. As a consequence a transmit slip will occur.
Transmit Offset
Calculation of delay time T (SCLKX cycles) depends on the value X
of the “Transmit Offset” register XC(1:0):
0

with maximum delay = (256
with SC = system clock defined by SIC1.SSC(1:0)
with SD = 2.048 MHz
Delay time T = time between beginning of time slot 0 (bit 0, channel
phase 0) at XDI/XSIG and the initial edge of SCLKX after
SYPX/XMFS goes active.
