5.5.2.1 Registers used in Conjunction with the CS Handler
In detail, the following register bits are used in conjunction with the CS handler:
Signaling FIFO
CIFIFO
The 9 byte deep CIFIFO stores the addresses of CFI time slots in which a C/I and/or a
SIG value change has taken place. This address information can then be used to read
the actual C/I or SIG value from the Control Memory.
SBV:
SAD6 … 0:
Timer Register
TIMR
The EPIC timer can be used for 3 different purposes: timer interrupt generation
(ISTA:TIG), FSC multiframe generation (CMD2:FC2 … 0 = 111), and last look period
generation.
In case of last look period generation, the following functions are provided:

Signaling Byte Valid; if SBV = 1, the SAD6 … 0 bits indicate a valid
subscriber address. The polarity of SBV is chosen such that the
whole 8 bits of the CIFIFO can be copied to the MAAR register in
order to read the upstream C/I or SIG value from the Control Memory.
Subscriber Address bits 6 … 0; The CM address which corresponds
to the CFI time slot where a C/I or SIG value change has taken place
is encoded in these bits. For C/I channels SAD6 … 0 point to an even
CM address (C/I value), for SIG channels SAD6 … 0 point to an odd
CM address (stable SIG value).
Signaling Sampling Rate; If SSR = 1, the last look period is fixed to
125 s, i.e. the timer is not used at all for the last look logic. The value
programmed to TVAL has then no influence on the last look period.
The timer can then still be used for timer interrupt generation, and/or
FSC multiframe generation, with a period as defined by TVAL6 … 0.
If SSR = 0, the last look period is defined by TVAL6 … 0. Note that if
the timer is used, it must also be started with CMDR:ST = 1.
