7.20 Data Processing Instructions
Searching the maximum value of 32-bit binary data
DMAX(P)(_U)
These instructions search the (n) points of 32-bit binary data in the specified device for the maximum value.
*1 The DMAX and DMAX_U instructions do not support the ST and FBD/LD. Use the standard function, MAX.
