Receive CAS Register 1-16
Each register except RS1 contains the received CAS bits for two timeslots. The received
CAS multiframe will be compared with 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
RS1-16 register are ignored, the received data may be 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 RS1-
16 . Refer also to register RSP1/2.
Access to RS1-16 registers is only valid if the serial receive signaling access on the
system highway is disabled.
