NAME
DESCRIPTION
7-5
SAB2-0*
Source Stream Address bits.
These three bits are used together with SAB3 in CMH to
select up to 16 different source streams for the connection. Depending on the switching
configuration and the data rate selected in the application, 1, 2, 3 or all 4 SAB bits can be
used. See Tables 9 and 10 for details.
4-0
CAB4-0*
Source Channel Address bits 0-4.
These five bits are used together with CAB5-6 in
CMH to select up 128 different source channels for the connection. Depending on the
switching configuration and the data rate used in the application, 5, 6 or all 7 CAB bits
can be used to select respectively 32, 64 or 128 different channels.
See Tables 9 and 10 for details.
If bit two (MC) of the corresponding Connection High locations is 1, or if bit 6 of the Control Register is 1, then these entire eight bits are output
on the corresponding output channel and stream associated with this location. Otherwise, the bits are used as indicated to define the source
of the connection which is output on the channel and stream associated with this location.
