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 VDD or VSS
.
3. Preferable crystal types: MU206S and DMX38.
4. When running on RC oscillator, the input of the crystal oscillator must be connected to VDD or VSS
.

The RC oscillator frequency tolerance ∆fosc
=
∆Rosc2 + ∆Cosc2 + (0.05 × fosc
)
6. Below this maximum value the IC will detect an oscillator fault.
