Operands:
S
: Starting source address
D
: Destination address for the result
n
: Length of the
S
file
Description:
1. The instruction obtains the mean value from
n
consecutive registers from
S
and stores the
value in
D
.
2. Remainders in the operation will be ignored.
3. If
n
is out of the valid range (1~64), an error will be generated.
4. If operands
D
,
n
use index F, then only 16-bit instruction is available.
5. Valid range of operand
n
:
n
=1~64
Program Example:
When X20 = ON, add up the contents of the three registers starting from D0, and divide the sum
by three to get the mean value. Store this mean value in D10 and ignore the remainder.
