DSP6416T-DATASHEET上说,RESET 信号变高后,有16070P个时间,ECLKOUT1才有效,DSP程序若在这之前去操作EMIFA外设,是不是没有效果?

Hi zz zh,
During the delay period the C6416T is still in an internal reset state. The EMIFA can't be used during this state and can't be used until it is programmed by the boot code. The device will boot from either HPI or EMIFB so the delay of the output of AECLKOUT1 shouldn't have any effect.
