您好:
我想请教下PWM的TZ(trip-zone)是怎么用的,6个TZ分别接到片子上的哪6个IO口的?这一部分看手册不是很明白。
谢谢您的指导。
以下内容是trip zone模块的功能,GPIO12到GPIO17和6个TZ引脚是复用的。
Trip inputs TZ1 to TZ6 can be flexibly mapped to any ePWM module.
• Upon a fault condition, outputs EPWMxA and EPWMxB can be forced to one of the following:
– High
– Low
– High-impedance
– No action taken
• Support for one-shot trip (OSHT) for major short circuits or over-current conditions.
• Support for cycle-by-cycle tripping (CBC) for current limiting operation.
• Each trip-zone input pin can be allocated to either one-shot or cycle-by-cycle operation.
• Interrupt generation is possible on any trip-zone pin .
• Software-forced tripping is also supported.
• The trip-zone submodule can be fully bypassed if it is not required.
谢谢。那datasheet中下面这段话怎么理解呢?
TZ1–6 (Trip Zone)inputs come from GPTRIP1–3 (from GPIO_MUX1),EQEPERR(from the eQEPperipheral),CLOCKFAIL(from M3CLOCKS),andEMUSTOP(from the C28x CPU).
