I want to use the uart communicate in a low power. In VLPR the UART moudle is active and the current is 2mA. In VLPS the UART is not work.
So Is there any other way that the UART can work and the power cost is low?
And in the VLPS mode the UART can work. Is the current is 2mA in the VLPS mode? If there is less than 2mA. Please send it to me the demo.
And in the VLPS mode. Use the fast IRC 4m no divide. I confige the baud. But the UART doesn't receive the right byte. Why this happen?
