A unique signaling pattern on the SDATA line while SCLK is held high, indicating the beginning of a frame.
Before the advent of SPMI, hardware designers relied on fragmented, proprietary interfaces or standard protocols like I2C and SPI to manage power. However, these older interfaces lacked the necessary bandwidth, real-time latency controls, and advanced interrupt structures required to dynamically scale voltages in microseconds. SPMI was built specifically to bridge this gap, standardizing how systems monitor and control voltage and current levels. 2. Key Features of the SPMI Architecture mipi spmi specification pdf
