AN1139: CP2615 I/O Protocol

PublishTime：2023-02-20

●The CP2615 I/O Protocol (IOP) is a stateless, message-based protocol designed specifically to provide access to the CP2615 I/O functions. The protocol is transported by USB bulk transfers over the CP2615 Serial Interface. It includes a notification capability that is designed to work seamlessly within the event driven architecture of a host application. The following features can be accessed using the CP2615 I/O Protocol:
■Query device identification information
■Query GPIO configuration
■Observe and control the GPIO.15-0 pins
■Observe the analog pin GPIO.8/ADC
■Receive autonomous notifications of GPIO/ADC changes
■Perform small transfers on the I²C bus
■Query error status of the I/O Protocol
●KEY POINTS
■This document describes the CP2615 I/O Protocol, transported by USB bulk transfers.
