有2个配置说明不是很明白,请教TI高手。
在EPWM REFERENCE中关于TZ模块有2段话:
1、If the CBC interrupt is enabled via the TZEINT register, and DCAEVT2 or DCBEVT2 are selected as CBC trip sources via the TZSEL register, it is not necessary to also enable the DCAEVT2 or DCBEVT2 interrupts in the TZEINT register, as the DC events trigger interrupts through the CBC mechanism.
2、If the one-shot interrupt is enabled via the TZEINT register, and DCAEVT1 or DCBEVT1 are selected as OSHT trip sources via the TZSEL register, it is not necessary to also enable the DCAEVT1 or DCBEVT1 interrupts in the TZEINT register, as the DC events trigger interrupts through the OSHT mechanism.
我的理解:
第1条:DCAEVT2和DCBEVT2是工作在CBC机制下的,如果DCAEVT2和DCBEVT2被配置成TZ模块的CBC触发事件,那么不用在TZEINT中使能中断?
第2条:DCAEVT1和DCBEVT1是工作在OST机制下的,如果DCAEVT1和DCBEVT1被配置成TZ模块的OST触发事件,那么不用在TZEINT中使能中断?
是不是这样理解????
那么关于
DC模块的DCAEVT2和DCBEVT2工作在CBC机制下是怎么回事?
DCAEVT1和DCBEVT1是工作在OST机制又是怎么回事?
