I am a beginner and I need answers to two questions.

Haoooo

1. The following program configures the DSP at two operating frequencies of 150MHz and 100MHz when the ideal baud rate is 9600 .

If the ideal baud rate is changed from 9600 to 57600 , how should the following program be modified? Please give the calculation process

2. Explain the meaning of the following timing diagrams of external interface modules

These are two relatively simple questions. I hope someone can help answer them. Thank you very much!!
