/* Flush serial buffer before deep sleep | ||
* | ||
* Since deepsleep() may shut down the UART peripheral, we wait for some time | ||
* to allow for hardware serial buffers to completely flush. | ||
* | ||
* Take NUMAKER_PFM_NUC472 as an example: | ||
* Its UART peripheral has 16-byte Tx FIFO. With baud rate set to 9600, flush | ||
* Tx FIFO would take: 16 * 8 * 1000 / 9600 = 13.3 (ms). So set wait time to | ||
* 20ms here for safe. | ||
* | ||
* This should be replaced with a better function that checks if the | ||
* hardware buffers are empty. However, such an API does not exist now, | ||
* so we'll use the busy_wait_ms() function for now. | ||
