Page 18: Serial Protocol
The I2C signal has 4 different kinds of frames (see table below). Every frame has 12 bytes of data which is 96'h53_49_47_4C_45_4E_54_5F_XX_XX_XX_XX（SIGLENT_XXXX in ASCII format, XXXX stands for 4 random characters）. If you have trouble in understanding the table below, please refer to NXP document UM10204. STB3 User Manual... -
