### 3.8.2 测试与作业 ###

> 下面关于FTFA模块的在线编程寄存器描述中正确的是  
> A.Flash状态寄存器给出当前FTFA模块的功能状态的信息。  
> B.通用命令参数寄存器给出FTFA模块的操作状态。  
> C.在复位过程中，Flash选项寄存器的值从Flash配置域中载入。  
> D.通用命令参数寄存器的D7位是命令完成中断标志位，用于标识一个flash命令是否完成。  
> 正确答案：C

> 1下面关于Flash驱动构件描述正确的有:  
> A.Flash具有初始化、擦除和写入、按逻辑地址读取、按物理地址读取、保护六种基本操作。  
> B.FTFA命令的操作主要包括载入命令到通用命令参数寄存器组、清CCIF位启动命令、执行命令与报错。  
> C.驱动构件功能函数放置在命名为flash.h的文件中。  
> D.对模块进行初始化，主要是判断和等待Flash操作命令完成、清相关的标志位、对杂项模块中平台控制寄存器的PLACR\_ESFC进行设置。  
> 正确答案：A、B、D

> 2写入函数与擦除函数类似，主要区别在于，擦除操作向目标地址中写0xFF，而写入操作需要写入指定数据。  
> A.B.  
> 正确答案：A

> 3KL系列MCU提供了哪些Flash在线编程的寄存器？  
> 正确答案：  
> 1个状态寄存器、1个配置寄存器、1个安全寄存器、1个选项寄存器、12个通用命令参数寄存器以及4个保护寄存器。
