4. Self-boot function description
(1)
Self-boot function
The TC9447F 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 formats: I
2
C and the original
mode. However, the boot must be executed in Standard Transmission (the original) mode.

Boot ROM format
The following shows the breakdown of the 18 bits.
00
Data that are being sent
01
Command
10
Final data (after the data are sent, the
CS
signal is set to “H”).
11
Jump address (jump to any address in the self-boot ROM).
Figure 2 Boot ROM Format and Example
Boot mode completes when the address reaches 3FFh, the maximum value.
Therefore, for the final address, write JMP 3FFh (data = 303FFh).
