6 2 3 5 ENCODING OF OPERATION DIRECTION
In many two-operand instructions the d field is pres-
ent to indicate which operand is considered the
source and which is the destination
6 2 3 6 ENCODING OF SIGN-EXTEND (s) FIELD
The s field occurs primarily to instructions with im-
mediate data fields The s field has an effect only if
the size of the immediate data is 8 bits and is being
placed in a 16-bit or 32-bit destination
6 2 3 7 ENCODING OF CONDITIONAL TEST
For the conditional instructions (conditional jumps
and set on condition) tttn is encoded with n indicat-
ing to use the condition (n
and ttt giving the condition to test
