Microcontroller interface
2.1
Standard Transmission Mode
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 TC9496AF loads the IFDI data on the IFCK signal rising edge.
When CS
= H, the IFCK and IFDI signals are don’t care.
2.1.1 Setting Registers
The registers are set by command data using IFDI signal.
The first byte is a command, which differs for each register. The data sent after that are fixed to
two bytes. Both command and data are sent starting from the MSB.
Data are loaded the rising edge of the IFCK signal. Note that commands or data that must be
switched, such as the RUN-MUTE command (command-44h) or the IFF flag, must be synchronized
with the SYNC signal and loaded on that signal.
