Hardware Description
CASMF
7
quarter or one eighth of the time slot. Data is not repeated. The time
while data is active during a 8
phase. RDO/RSIG are cleared (driven to low level) while XDI/XSIG
are ignored for the remaining time of the 8
remaining channel phases. The channel phases are selectable with
these bits.
000 = Data active in channel phase 1, valid if system data rate is
001 = Data active in channel phase 2, valid if system data rate is
010 =Data active in channel phase 3, valid if data rate is 16/8 Mbit/s
011 = Data active in channel phase 4, valid if data rate is 16/8 Mbit/s
100 = Data active in channel phase 5, valid if data rate is 16 Mbit/s
101 = Data active in channel phase 6, valid if data rate is 16 Mbit/s
110 = Data active in channel phase 7, valid if data rate is 16 Mbit/s
111 = Data active in channel phase 8, valid if data rate is 16 Mbit/s

The time slot 0 multiframe begin is asserted on pin RP(A to
D)/pin function RMFB.
The time slot 16 CAS multiframe begin is asserted on pin RP(A
to D)/pin function RMFB.
During incative channel phases, RDO and RSIG are switched
to low output level.
During incative channel phases, RDO and RSIG are switched
into tri-state mode.
Normal operation.
SEC/FSC output is switched into tri-state mode.
