* Pro-Micro DeepSleep Quick Fix It is noticed that some nRF52840 boards (pro-micro in particular) stopped waking up from the deep sleep state (shutdown state) with a press of a button. The problem is in a Serial1.end() call. * Clear GPREGRET before setting There are some troubles with that register: it is recommended to clear it with 0xFF mask and only after that perform a setting. * Pro-Micro button SENSE signal Added SENSE signal on the user button. It is explicitly enabled now for this platform. * nRF52 pre-sleep main serial check Added another usage check for the main Serial. It could save some nerves in case the port is not in use by any means. Applied trunk fmt to the file. --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com>
