Self-Boot Function Description
4.1
Self-Boot Function
The TC9496AF supports a self-boot function for setting coefficients and offsets.
As Figure 1 shows, the data are set via the microcontroller interface circuit.
First saving the data to be set via the microcontroller in the self-boot ROM (SBROM) allows various
modes to be set later. The microcontroller interface circuit supports two format: I2C and the original
mode. However, the boot must be executed in Standard Transmission.
All the command inputs from the exterior are disregarded during a boot term.
