I want to know how this calculation is done? For example, I set pSciRegs->SCIHBAUD = 0x0000; pSciRegs->SCILBAUD = 0x00C2; Why is the calculated SCI Asynchronous Baud = 9600? I set LSPCLK = 15MHz...
A few years ago, it was popular to hang a hook on the mobile phone that flashes when a call comes in. When a call comes in, the LED on the hook flashes. I guess the principle is that there is a chip o...
