The clock frequency is 11.0592M

Procedure 2

Use the dynamic scanning method and timer 1 to display the stopwatch in the first three digits of the digital tube,
accurate to 1% of a second, that is, the last digit displays 1% of a second, and the cycle continues.

Procedure 3

Using dynamic scanning and timer 1, the digital tube displays a number
starting from 765432 and decreasing at a speed of 1/10 second
until 765398 and keeps displaying this number. At the same time, using
timer 0 at a speed of 500MS, the running lights move from top to
bottom. When the number on the digital tube decreases to a stop,
the running lights on the experimental board also stop and then all start flashing. After 3 seconds
(using T0 timing), all the running lights turn off and the digital tube
displays "HELLO". Keep it here.
