To manage communication in a multi-device network, SPMI utilizes two tiers of addressing:

was designed as a two-wire, low-latency, high-speed serial interface specifically for power management. It is a hardware interface plus a command protocol that allows an application processor to read/write registers on multiple PMICs using a single bus.

Understanding the MIPI SPMI Specification: A Comprehensive Technical Guide

Utilizes a serial clock line (SCL) and a serial data line (SDA) to minimize PCB trace routing and pin counts [1]. To manage communication in a multi-device network, SPMI

The bus can accommodate up to 4 master devices and 16 slave devices , allowing complex chipset partitioning.

The protocol uses odd parity for error detection and includes ACK/NACK bits in version 2.0 to confirm successful frame reception. Applications and Industry Use System Power Management - MIPI SPMI - MIPI.org How to Access the PDF Understanding the MIPI

Driven by the active master device to synchronize data transfers across the bus.

Features an advanced arbitration mechanism to ensure critical power commands (like emergency shutdowns or voltage scaling) take precedence.
