高速PWM引脚怎么切换

您好，我是大约一半通过一个项目，它是使用高速PWM引脚控制谐振功率转换器，使用DSSPICEP16GS506。我想启动“手动”转换器使用A/D触发开关定时，然后移到PWM引脚。家庭手册说，在PWM模块接通时，不必调整控制引脚所有权的位，但是ErATM建议这种方法作为解决一些硅问题的方法。如果我继续使用软件转换，大家都认为，未来的硅版本会给我带来麻烦吗？我总是可以使用外部MUX来改变引脚，但这意味着重新布局的董事会。

    Hello,
I am arround half way through a project which is using the high speed PWM pins to control a resonant power converter, using a dspic33ep16gs506.  I want to start the converter "manually" using the A/D to trigger switch timings then move over to the PWM pins.  The family manual says that the bits controlling the ownership of the pins must not be adjusted while the pwm module is switched on, but the eratum suggests this method as a work around for some of the silicon issues.  If I go ahead wth my deisgn and use software switching, am I likely to get into trouble with future releases of silicon, in everyone's opinion?  I could always use an external MUX to change over the pins but that means a re-layout of the board.
