The IFDI signal is the data.
sent after that are fixed to two bytes. Both command and data are sent starting from the MSB in I
format.
the SYNC signal, such as the RUN command or the IFF flag, must be synchronized with the SYNC
signal and loaded on that signal.

C Bus Mode
When I2CS = H, data can be transmitted or received in I
When the CS signal is Low, control from the microcontroller is enabled.
In I
The TC9496AF loads the IFDI data on the IFCK signal rising edge.
When CS = H, IFCK and IFD signal are don’t care.
The register are set by command data using the IFDI signal.
The first byte after the I
The data loaded internally every two bytes. Note that commands or data that must be switched on
