4.2.3.7
Due to signaling procedures using the five S
CRC multiframe structure, three possibilities of access by the microprocessor are
implemented.
• The standard procedure allows reading/writing the S
• The advanced procedure, enabled by bit FMR1.ENSA, allows reading/writing the S
A transmit or receive multiframe begin interrupt (ISR0.RMB or ISR1.XMB) is provided.
Registers RSA(8:4) contains the service word information of the previously received
CRC-multiframe or 8 doubleframes (bit slots 4 to 8 of every service word). These
registers are updated with every multiframe begin interrupt ISR0.RMB.
With the transmit multiframe begin an interrupt ISR1.XMB is generated and the contents
of the registers XSA(8:4) is copied into shadow registers. The contents is subsequently
sent out in the service words of the next outgoing CRC multiframe (or every
doubleframe) if none of the time slot 0 transparent modes is enabled. The transmit
multiframe begin interrupt XMB request that these registers issue should be serviced. If
requests for new information are ignored, the current contents is repeated.
• The extended access through the receive and transmit FIFOs of the signaling

SA62, SA63, SA64 = 1000, 1010, 1100, 1110, 1111. All other possible 4-bit
combinations are grouped to status “X”.
A valid S

During the basic frame asynchronous state update of register RSA6S and interrupt
status ISR0.SA6SC is disabled. In multiframe format the detection of the S
combinations can be done either synchronously or asynchronously to the submultiframe
(FMR3.SA6SY). In synchronous detection mode updating of register RSA6S is done in
the multiframe synchronous state (FRS0.LMFA = 0). In asynchronous detection mode
updating is independent of the multiframe synchronous state.
