各位侠客们好,有个小小的疑问,手册spruh22c(April 2012–Revised February 2013)中描述的C28核DMA模块的MODE寄存器中没有关于SYNCE、SYNCSEL这两个bit的描述,而F28M35x_DMA.c文件中却有对这两个bit的定义DmaRegs.CH1.MODE.bit.SYNCE = synce; DmaRegs.CH1.MODE.bit.SYNCSEL = syncsel;请教在哪可以找到对这两个bit的描述,谢谢!
hongyue,
F28335比较早出,piccolo和concerto的外设都有相对于F28335做一些优化,比如PWM, ADC等模块最明显。你可以看一下28069也没有这两个位。所以DMA Mode寄存器在Piccolo和concerto上的那两个位配置是没有的。
