Notes
1. The IC is programmed to standby mode via the I²C-bus command, no LED is connected, no I²C-bus communication,
one oscillator is running and the Watchdog timer is disabled.
2. When running on crystal oscillator, the input of the RC oscillator must be connected to V_DD or V_SS.
3. Preferable crystal types: MU206S and DMX38.
4. When running on RC oscillator, the input of the crystal oscillator must be connected to V_DD or V_SS.
5. The RC oscillator frequency f_osc = _R-----o---_s--0-_c--.-_×-8---7-C-----_o---_s--_c-
The RC oscillator frequency tolerance ∆f_osc =
