 The data of V1 and V2 will be exchanged after executing XCHG command.
Example
Exchange the data of $11 and $2 (this is an operation of unsigned 16-bit data).
If $11 = 1234H and $2 = 5678H, $2 = 1234H and $1 = 5678H after executing XCHG
command.
 MAX (Get Maximum Value of a Range of Data)
Equation
Var1 = MAX (Var2, Var3)
Explanation
Get the maximum value from Var2 and Var3 and store the result in Var1.
Remark
 The calculation result can be stored as signed or unsigned WORD and DWORD.
 Var1 can be internal memory only. Var2 and Var3 can be internal memory or
constant.
Example
Get the maximum value from $0 and $1 and store the result in $2 (this is an
operation of unsigned 16-bit data).
If $0 = 2 and $1 = 10, $2 = 10 after executing MAX command.
