Depending on the RP(A-D) pin function different offsets could be
programmed. The SYPR and the RFM pin function could not be
selected in parallel.
Receive Offset (PC(1-4).RPC(2-0) = 000)
Initial value loaded into the receive bit counter at the trigger edge of
SCLKR when the synchronous pulse at port SYPR is active (see
figure 51).
Calculation of delay time T (SCLKR cycles) depends on the value X
of the „Receive Offset“ register RC1/0. Refer to register RC1.
