STV82x7 Reset
All STV82x7 features are controlled via the I²C bus.
The STV82x7 can be "reset" in 2 ways:
1. By Software via the I²C bus: This clears all synchronous logic, except for the I²C bus registers.
2. By Hardware via the RESET pin: In addition to clearing all synchronous logic, the RESET input
(active on the low level) resets all the I²C bus registers to the default values listed below.
