REGISTER_B[1..3] must be set
similar to the value of INPUT_
REGISTER_B0.
INPUT_ACLR_A0 String No Specifies the asynchronous clear
for the dataa[] operand of the
first multiplier. Values are ACLR0,
ACLR1, ACLR2, and ACLR3. If
omitted and corresponding
INPUT_REGISTER_A[] is used, the
default value is ACLR3.
INPUT_ACLR_A1 String No Specifies the asynchronous clear
for the dataa[] operand of the
second multiplier. Values are
