I2S Protocol Question & Answers August 8, 2022 By WatElectronics This article lists 75 I2S protocol MCQs for engineering students. All the I2S protocol Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the I2S protocol. I2S protocol stands for Inter IC Sound which is an electrical serial interface used for producing digital audio signals. The I2S bus splits up the clock and periodic data signals. I2S protocol has three different lines in the timing figure such as Word select, serial clock, and serial data. Word clock line bit 0 is called the left channel. Word select bit 1 is called the right channel. The behavior of word select lines is correlated to audio channels. For designing challenges, Oscilloscopes are used for handling signal unity and timing techniques. I2S enforces Easy type DMA for sample shifting directly to & from RAM beyond CPU intervention. There exist different registers in the I2S bus interface such as the I2S_Status register, and the I2S_Control register. The register data will be read with the I2S_ReadTxStatus() Application interface function. Transmission data was drafted to the STDOUT at the falling edge of the I2S Serial clock. Word selection may alter whether on a trailing/leading edge of the periodic clock, but it will not require it to be symmetrical. Inter IC Sound supports both half and full duplexes. Name Email 1).
