^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) On reading represents the current state of the bus. If it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) contains a "0" the bus is stopped and connected devices are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) expected to not do anything because their watchdog triggered.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) When the file contains a "1" the bus is operated and periodically
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) does a push-pull cycle to write and read data from the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) connected devices.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) When writing a "0" or "1" the bus moves to the described state.
