目录硬知识Timer_B特点及结构Timer_B寄存器定时器B API处理计时器配置和控制的函数参数处理计时器输出的函数参数管理定时器B中断的函数参数平台Code Composer Studio 10.3.1 MSP430F5529 LaunchPad™ Development Kit (MSP‑EXP430F5529LP) 硬知识 16位定时器B(Timer_B)和Timer_A一样是MSP430单片机的重要资源。Timer_B往往比Timer_A功能更强大一些MSP430F5529单片机的Timer_B定时器具有7个捕获/比较寄存器。
Timer_B特点及结构 Timer_B定时器具有以下特点 具有4种工作模式和4种可选计数长度的异步16位定时/计数器 参考时钟源可配置 高达7个可配置的捕获/比较寄存器 具有PWM输出能力 具有同步加载能力的双缓冲区比较锁存 具有可对Timer_B中断快速响应的中断向量寄存器。 Timer_B和Timer_A的不同之处列举如下 ① Timer_B计数长度为8位、10位、12位和16位可编程而Timer_A的计数长度固定为16位。 ② Timer_B没有实现Timer_A中的SCCI寄存器位的功能。 ③ Timer_B在比较模式下的捕获/比较寄存器功能与Timer_A的不同增加了比较锁存器。 ④ 有些型号芯片中的Timer_B输出实现了高阻抗输出。 ⑤ 比较模式的原理有所不同。在Timer_A中CCRx寄存器中保存与TAR相比较的数据而在Timer_B中CCRx寄存器中保存的是要比较的数据但并不直接与定时计数器TBR相比较而是将CCRx送到与之相对应的锁存器之后由锁存器与定时计数器TBR相比较。从捕获/比较寄存器向比较锁存器传输数据的时机也是可以编程的可以是在写入捕获/比较寄存器后立即传输也可以由一个定时事件来触发。 ⑥ Timer_B支持多种、同步的定时功能多重的捕获/比较功能和多重的波形输出功能。而且通过对比较数据的两级缓冲可以实现多个PWM信号周期的同步更新。
Timer_B寄存器
Timer_B寄存器列表如表所示基址为03C0h。
