DRIVING INTEGRATED CIRCUIT AND UPATE METHOD THEREOF

摘要

A driving IC is being controlled by a host IC to update a driving program stored in a storage with a SPI interface. The driving IC includes a IIC interface, an identifying module, and a calculating module. The IIC interface receives an instruction from the host IC in the IIC protocol format. The identifying module determines whether the received instruction is an update instruction, and generates a converting instruction when the received instruction is the update instruction. The calculating module converts the received instruction into a SPI format according to a predetermined converting rule. The SPI interface transmits the converted instruction in the SPI format to the storage.

1. A driving integrated circuit (IC), being controlled by a host IC to update a driving program stored in a storage with a single program initiation (SPI) interface, the driving IC comprising:
an inter-IC (IIC) interface to received an instruction from the host IC in the IIC protocol format; an identifying module to determine whether the received instruction is an update instruction, and generate a converting instruction when the received instruction is the update instruction; and a calculating module to convert the received instruction into an SPI format according to a predetermined converting rule; and an SPI interface to transmits the converted instruction in the SPI format to the storage.
