微型计算机的CPU在工业应用中对字节操作数进行数据计算时速度快、效率高。但微控制器除与字节变量打交道外,还常常需要处理位变量。在现实生活中,许多事物只有两种状态。例如,开关触点非分即合,指示灯不明则暗,马达或运行或停止,等等。Mcs-51把这些一位变量,即布尔变量,作为一个单独数据类型给予完全的硬件支撑。如果说位处理能力
Microcomputer CPU in industrial applications for byte operand data calculation speed, high efficiency. However, in addition to dealing with the byte variable microcontroller, but also often need to deal with bit variables. In real life, many things have only two states. For example, the switch contact point, the indicator is unknown dark, the motor is running or stopped, and so on. Mcs-51 gives these one variable, the Boolean variable, a complete hardware support as a single data type. If you say bit processing power
