configuration for 1Mhz

[KVK012]

I have tested your code and it is working fine if clock freq is 16Mhz.
If I set 1Mhz clock the code is not working
I changed value from 16000 to 1000 at TA1CCR0 = 1000u; but what to set at one more condition as shown below.
if (TA1CCR0 > 750)
{
...
...
}
Please guide.

This was all based on SMCLK ticking at 16 MHz. You could divide everything by 16 if SMCLK is running at 1 MHz, and it should just work. So in that captured edge value comparison (TACCR0>750) you could try 47 and everything else should follow.

Hi,
Thanks for reply.
I already tried that but it is not working. Would you like to suggest anything else? I will try.

Are you setting up DCO at 1 MHz and sourcing both MCLK and SMCLK from it? Other than that, just make sure you're setting up USCI_A0 correctly for the 1 MHz clock and your desired baud rate.
