Deserial Serial Peripheral Interface (DSPI)
16.1 Introduction
16.1.1 Overview
The Deserial Serial Peripheral Interface (DSPI) module provides a synchronous serial bus for
communication between an SoC and an external peripheral device.
The PXS20 device has three DSPI modules, referred to as DSPI_0, DSPI_1, and DSPI_2.
The DSPI modules interact with the CTU as described in Section 13.4.1, Interaction with other
peripherals.
Figure 16-1 is a block diagram of the DSPI module.
