two_byte_form I2
Description:
The minimum of the two source operands is placed in the result register. In the
one_byte_form, each unsigned 8-bit element of GR
r
2
is compared with the
corresponding unsigned 8-bit element of GR
r
3
and the smaller of the two is placed in
the corresponding 8-bit element of GR
r
1
. In the two_byte_form, each signed 16-bit
element of GR
r
2
is compared with the corresponding signed 16-bit element of GR
r
3
and
the smaller of the two is placed in the corresponding 16-bit element of GR
r
1
.
