- A FLASH Bootloader for PIC16 and PIC18 Devices--硬译（一）

currently in memory will be executed as if it were just received.
接收/发送缓冲区的一个很有用的特性就是它的内存保留在包之间,从而允许非常
快速重复和复制操作。也就是说, 如果一个空包被发送, 现有的数据在内存中被收到将会很快被执行。

COMMAND INTERPRETER（ 命令解释器）

The command interpreter decodes and executes ten different commands, seven base commands 
and three special commands. 
命令解释器解码并执行10个不同的命令，7个基础命令和3个特殊命令。
A complete list of the commands is provided in Appendix A.
一个完整的命令列表在附录A中提供。
The base commands allow for read, write, and erase operations on all types of non-volatile memory. 
最基础的命令在非易失性内存上允许读、写和擦除操作。
The other three commands are for special operations, such as repeating the last command, replicating 
the data, and resetting the device.
其他三个命令为特殊操作，比如重复最后一个命令，拷贝其他数据或者是复位器件。
Note that the PIC18F devices have greater access to, and control of, memory than PIC16F devices. For
example, PIC16F devices do not have access to the configuration memory, thus they do not use the 
configuration commands. Therefore, not all instructions are available in the PIC16F bootloader.
注意,PIC18F器件比PIC16F有更大的访问,和控制、存储能力。比如PIC16F器件没有访问并配置内存, 因此

他们不得使用配置命令。
