I2C bus mode
When I2CS = H, data can be transmitted or received in Standard Transmission mode.
When the CS signal is Low, control from the microcontroller is enabled.
In I2C mode, the CS signal can be used fixed to L.
The IFCK signal is the transmit/receive clock. The IFDI signal is the data. The TC9447F loads the
IFDI data on the IFCK signal rising edge. When CS = H, the IFCK and IFDI signals are don't care.
(3-1) Setting registers
The registers are set by command data using the IFDI signal. The first byte after the I2C address
(32h) 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 in I2C format.
The ACK pin cannot be used in I2C format. However, the acknowledge signal can be read by
using data signals in I2C format. The data are loaded internally every two bytes.
Note that commands or data that must be switched on the SYNC signal, such as the RUN
command or the IFF flag, must be synchronized with the SYNC signal and loaded on that signal.
(3-2) Setting RAM (sequential)
The RAMs are set by command data using the IFDI signal.
The first byte after the I2C address (32h) is a command, which differs for each RAM. The next two
bytes contain the start address for the RAM to be written to. The length of the data field following
the RAM address bytes is 2 × n bytes. The address is automatically incremented by 1.
