If bit 15 of C is ON and more than one address contains the same maximum val-
ue, the position of the lowest of the addresses will be output to D+1.
The number of words within the range (N) is contained in the 3 rightmost digits of
C, which must be BCD between 001 and 999.
When bit 15 of C is OFF, data within the range is treated as normal binary and
when it is ON the data is treated as signed binary.

Caution If bit 14 of C is ON, values above #8000 are treated as negative numbers, so the
results will differ depending on the specified data type. Be sure that the correct
data type is specified.
Flags ER: Indirectly addressed DM word is non-existent. (Content of DM word is
not BCD, or the DM area boundary has been exceeded.)
The number of words specified in C is not BCD (000 to 999).

for the address that contains the minimum value and outputs the minimum value
to the destination word (D).
If bit 14 of C is ON, MIN(––) identifies the address of the word containing the
minimum value in D+1. The address is identified differently for the DM area:
1, 2, 3... 1. For an address in the DM area, the word address is written to D+1. For ex-
ample, if the address containing the minimum value is DM 0114, then #0114
is written in D+1.
