Receive Offset/Receive Frame Marker Offset
Depending on the RP(A to D) pin function different offsets can be
programmed. The SYPR and the RFM pin function cannot be
selected in parallel.
Receive Offset (PC(4:1).RPC(2:0) = 000)
Initial value loaded into the receive bit counter at the trigger edge of
SCLKR when the synchronous pulse on port SYPR is active.
Calculation of delay time T (SCLKR cycles) depends on the value X
of the receive offset register RC(1:0):
system clocking rate: modulo 2.048 MHz (SIC2.SSC2 = 0)
0
5
with maximum delay = (256 SC/SD) -1
with SC = system clock defined by SIC1.SSC(1:0)+SIC2.SSC2
with SD = system data rate
or
system clocking rate: modulo 1.544 MHz (SIC2.SSC2 = 1)
0
5
with maximum delay = 193 SC/SD - 1
with SC = system clock defined by SIC1.SSC(1:0)+SIC2.SSC2
with SD = system data rate
Delay time T = time between beginning of time slot 0 at RDO and the
initial edge of SCLKR after SYPR goes active.
