应该是没有完全一直的参数,只能是参考手册12.10的内容,下面是工程师的回复:
I do not know of an SCI specification that matches the parameter in the images you shared. Are you referring to the SCI sampling error tolerance? The SCI module samples using the SCICLK and a 'majority vote' logic as described in the device TRM:
While there is no spec for this (depends on other variables such as your baud rate, clock dividers, etc.) the SCI clock cycles that surround cycles 4, 5, and 6 in the image above would allow for some error tolerance. Is this information helpful at all to what you are looking for?
