$1 = NOT $0 Store the result of $1. $0 = F100H, $1 = 0EFFH.
Perform the logical NOT operation on $2, and save the result in $4 (this is an
operation of signed 32-bit data).
$4 = NOT $2 (Signed DW) Store the result of $4. $2 = F100 F100H, $4 = 0EFF 0EFFH.
 << (SHL, Logical Shift-left operation)
Equation
Var1 = Var2 << Var3
Explanation
Shift Var2 (WORD/DWORD) data to left (number of bit is Var3). The result of this
calculation is stored in Var1.
Remark
 The calculation result can be stored as WORD and DWORD.
 Var1 can be internal memory only. Var2 and Var3 can be internal memory or
constant.
Example
$0 = F100H
Shift-left 4 bits and becomes $1 = 1000H (this is an operation of unsigned 16-bit
data).
