Memory Mapped IO

I designed a memory mapped rv32 core with a simple memory controller and UART peripheral.

The thing confusing me is that should i set a "UART start transmit" bit in control register or i use "memory write" signal which generated by "S-Type instruction" for start transmitting?

Thank you!

At a time when the Indian stock market is peaking and has rallied immensely compared to global markets, there are companies that have not performed in the last 10 years. These are definitely a minor portion of the market considering there are hundreds of stocks that have turned multibagger since 2020. What went wrong with these stocks? Reasons vary from corporate governance, sectoral weakness, company specific and so on. But the more important question is, are these stocks worth buying?
