Receiving UART data while in stop mode

A battery device should sleep in stop mode but still catch commands arriving at 9600 baud. Which design works on many low-power STM32 parts?

A.Keep the normal UART running from the PLL during stop modeB.Clock an LPUART from the 32.768 kHz LSE so it can wake the coreC.Poll the RX pin once per second from an RTC wake-up interruptD.Change the link to SPI with a 1 MHz clock from the modem
