Receive CAS Register (16:1)
Each register except RS1 contains the received CAS bits for two time slots. The received
CAS multiframe is compared to the previously received one. If the contents changed a
CAS multiframe changed interrupt (ISR0.CASC) is generated and informs the user that
a new multiframe has to be read within the next 2 ms. If requests for reading the
RS(16:1) register are ignored, the received data is lost. RS1 contains frame 0 of the CAS
multiframe. MSB is received first.
Additionally a receive signaling data change pointer indicates an update of register
RS(16:1). Refer also to register RSP(2:1).
Access to RS(16:1) registers is only valid if the serial receive signaling access on the
system highway is disabled.
