AVG(––)
S
N
D
This instruction is available in the CPM2A/CPM2C only.
S must be hexadecimal.
N must be BCD from #0001 to #0064.
D and D+N+1 must be in the same data area.
DM 6144 to DM 6655 cannot be used for S, N, or D to D+N+1.
AVG(––) is used to calculate the average value of S over N cycles.
When the execution condition is OFF, AVG(––) is not executed.
Each time that AVG(––) is executed, the content of S is stored in words D+2 to
D+N+1. On the first execution, AVG(––) writes the content of S to D+2; on the
second execution it writes the content of S to D+3, etc. On the N
AVG(––) writes the content of S is stored in D+N+1, AVG(––) calculates the av-
erage value of the values stored in D+2 to D+N+1, and writes the average to D.

If there are two words containing
the minimum value, the one found
first will be stored in DM 0501.
