1 System Overview
1.1 Introduction
This guide is for those who want to implement HCC Embedded's USB host stack with NXP Semiconductors'
ISP1161 and ISP1161A1 USB host controllers.
The module provides a high speed USB 2.0 host controller which provides both full and low speed USB
functions. The controller can handle all USB transfer types and, in conjunction with the USB host stack, can
be used with any USB class driver.
The position of the host controller within the USB stack is shown below:
