Data Control Instructions Section 3-17
Description For the first N–1 cycles when the execution condition is ON, AVG(195) writes
the values of S in order to words starting with R+2. The Previous Value
Pointer (bits 00 to 07 of R+1) is incremented each time a value is written. Until
the Nth value is written, the contents of S will be output unchanged to R and
the Average Value Flag (bit 15 of R+1) will remain OFF.
When the Nth value is written to R+N+1, the average of all the values that
have been stored will be computed, the average will be output to R as an
unsigned binary value, and the Average Value Flag (bit 15 of R+1) will be
turned ON. For all further cycles, the value in R will be updated for the most
current N values of S.
The maximum value of N is 64. If more than 64 cycles are specified, the set-
ting will be treated as 64 cycles.
The Previous Value Pointer will be reset to 0 after N–1 values have been writ-
ten.
The average value output to R will be rounded to the nearest integer.
