Searching the maximum value of 16-bit data
MAX(P)(_U)
These instructions search the maximum value from the (n) point(s) of 16-bit binary data in the device starting from the one
specified by (s), and store the maximum value in the device specified by (d).
*1 The MAX(_U) instructions are not supported by the ST language. Use MAX of the standard function.

■Descriptions, ranges, and data types
■Applicable devices
• These instructions search the maximum value from the (n) point(s) of 16-bit binary data in the device starting from the one
specified by (s), and store the maximum value in the device specified by (d). These instructions start searching from the
device specified by (s), and store the location from (s) of the first maximum value in (d)+1 and the number of maximum
values in (d)+2.
