TMS320F28377D 用户手册DMA部分

Figure 5-5 DMA State Diagram

我对下面这两个箭头地方不甚理解,这两个方向都没条件,到底该走哪个方向呢

我理解的应该是如下图所示

望大佬们指点一下

  • 你好,芯片TRM中有关于HALT点的介绍:
    The HALT points represent where the channel halts operation when interrupted by a high priority channel 1 trigger, or when the HALT command is set, or when an emulation halt is issued and the FREE bit is cleared to 0.
    即,当被高优先级通道1触发器中断时,或当设置了HALT命令时,或当发出模拟停止且FREE 位被清0时,这个通道是不通的
