It is known that an 8-bit embedded computer system uses a 6-bit, 7-segment common-cathode led as an output device, and uses a dynamic display interface circuit. If the "visual retention" effect of the human eye is maintained for about 0.24 seconds, then the program control the six 7-segment led for stable display at the same time, what is the required maximum delay time after outputting a segment code and position code of a 7-segment led( )
