switched, such as the RUN-MUTE command (command-44h) or the IFF flag (command-4Ah), must be
synchronized with the SYNC signal and loaded on that signal.
When I2CS = “L”, data can be transmitted or received in Standard Transmission mode.
When the CS signal is Low, control from the microcontroller is enabled.
The IFCK signal is the transmit/receive clock.
The IFDI signal is the data. The TC94A04AF/AFD loads the IFDI signal on the IFCK signal rising
When CS = “H”, the IFCK and IFDI signals are don’t care.
The registers are set by command using the IFDI signals.
The first byte is a command, which differs for each register. The data sent after that are fixed to
Data are loaded the rising edge of the IFCK signal. Note that commands or data that must be
