TMS320x2833x, 2823x Enhanced Pulse Width Modulator (ePWM) Module 中使用EPWMxSYNCI: Synchronization Input Pulse 和Time-base synchronization input output (EPWMxSYNCO) signals ，對(duì)應(yīng)引腳為GPIO6（EPWMxSYNCI/EPWMxSYNCO）還有GPIO32和GPIO33?？梢越油獠棵}沖來同步。另有EPWMxSYNCI Synchronization Pulse:Writing a 1 to the TBCTL[SWFSYNC] control bit invokes a software forced synchronization. This pulse is ORed with the synchronization input signal, and therefore has the same effect as a pulse on EPWMxSYNCI.nWhen BCLKSYNC = 0, the time-base clock of all ePWM modules is stopped (default). When TBCLKSYNC = 1,all ePWM time-base clocks are started with the rising edge of TBCLK aligned.所以就不必外接EPWMxSYNCI/EPWMxSYNCO 脈沖產(chǎn)生電路，直接TBCLKSYNC = 1，就可以同步了。大家如何看這個(gè)問題呢？
