Disables Viterbi side effects.
Enables Viterbi side effects.
The
cmp0( )
,
cmp1( )
, and
cmp2( )
functions select minimum of input operands.
The
cmp0( )
,
cmp1( )
, and
cmp2( )
functions select maximum of input operands.
The traceback encoder stuffs one traceback bit into
ar0
for the
cmp1( )
function or
stuffs one old traceback bit from
ar0
into
ar1
for the
cmp0( )
function
(GSM/IS95-compatible mode).
The traceback encoder stuffs two traceback bits into
ar0
for the
cmp1( )
function or
stuffs two old traceback bits from
ar0
into
ar1
for the
cmp0( )
function
(IS54/IS136-compatible mode).
Reserved—write with zero.
Previous value of CFLAG0. The traceback encoder copies the value of CFLAG0 to
CFLAG1 if the DAU executes a
cmp2( )
function and VEN=1.
Previous value of CFLAG
. The traceback encoder copies the value of CFLAG to
CFLAG0 if the DAU executes a
cmp2( )
function and VEN=1.
For the
cmp2(aSE,aDE)
function, CFLAG=0 if MAX=0 and aSE
aDE or if MAX=1 and aSE
<
aDE, and CFLAG=1 if MAX=0 and aSE
<
aDE
or if MAX=1 and aSE
