Introduction

Doc ID 15457 Rev 8

25/160

A DSPI module provides these features:

●

Full duplex, synchronous transfers

●

Master or slave operation

●

Programmable master bit rates

●

Programmable clock polarity and phase

●

End-of-transmission interrupt flag

●

Programmable transfer baud rate

●

Programmable data frames from 4 to 16 bits

●

As many as 8 chip select lines available, depending on package and pin multiplexing

●

4 clock and transfer attributes registers

●

Chip select strobe available as alternate function on one of the chip select pins for de-

glitching

●

FIFOs for buffering as many as 5 transfers on the transmit and receive side

●

Queueing operation possible through use of the eDMA

●

General purpose I/O functionality on pins when not used for SPI

FlexPWM

The pulse width modulator module (FlexPWM) contains four PWM channels, each of which

is configured to control a single half-bridge power stage. Two modules are included on

LFBGA257 devices; on the LQFP144 package, only one module is present. Additionally,

four fault input channels are provided per FlexPWM module.

This PWM is capable of controlling most motor types, including:

●

AC induction motors (ACIM)

●

Permanent Magnet AC motors (PMAC)

●

Brushless (BLDC) and brush DC motors (BDC)

●

Switched (SRM) and variable reluctance motors (VRM)

●

Stepper motors
