-/* 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.
