TMS320F28388D: 关于26.4 Time-Base (TB) Submodule章节的疑问

Part Number: TMS320F28388D


问题1.请问这里是不是应该为“B减1”

按照寄存器定义,假设A为ePWM0,希望链接的是ePWM3,即B=3,那么向A的link寄存器写入的数值应该为2(B减1)而不是B+1

问题2. 26.4.3.4 ePWM SYNC Selection这个章节只有一个Table 26-3. ePWM SYNC Selection,但是其描述为“Table 26-3 specifies the sources for the ePWM SYNC input and output.”那么这个别个到底是描述input的还是output的呢?

下图为EPWMSYNCINSEL寄存器定义

Table 26-3EPWMSYNCINSEL寄存器有什么联系吗?

我看不懂Table 26-3要描述的是什么
