rates of up to 1 megabit per second (Mbps). The DCAN is ideal for applications operating in noisy and

harsh environments (e.g., automotive and industrial fields) that require reliable serial communication or

multiplexed wiring. The MibSPI provides a convenient method of serial interaction for high-speed

communications between similar shift-register type devices. The MibSPI provides the standard SOMI,

SIMO, and SPI clock interface as well as up to eight chip select lines.

The HET is an advanced intelligent timer that provides sophisticated timing functions for real-time

applications. The timer is software-controlled, using a reduced instruction set, with a specialized timer

micromachine and an attached I/O port. The HET can be used for compare, capture, or general-purpose

I/O. It is especially well suited for applications requiring multiple sensor information and drive actuators

with complex and accurate time pulses. The TMS470M HET peripheral contains the XOR-share feature.

This feature allows two adjacent HET high- resolution channels to be XORed together, making it possible

to output smaller pulses than a standard HET.

The TMS470M devices have one 10-bit-resolution, sample-and-hold MibADC. Each of the MibADC

channels can be grouped by software for sequential conversion sequences. There are three separate

groupings, all three of which can be triggered by an external event. Each sequence can be converted

once when triggered or configured for continuous conversion mode.

The frequency-modulated zero-pin phase-locked loop (FMzPLL) clock module contains a phase-locked

loop, a clock-monitor circuit, a clock-enable circuit, and a prescaler. The function of the FMzPLL is to

multiply the external frequency reference to a higher frequency for internal use. The FMzPLL provides the

input to the global clock module (GCM). The GCM module subsequently provides system clock (HCLK),

real-time interrupt clock (RTICLK), CPU clock (GCLK), HET clock (VCLK2), DCAN clock (AVCLK1), and

peripheral interface clock (VCLK) to all other TMS470M device modules.

The TMS470M devices also have an external clock prescaler (ECP) module that when enabled, outputs a

continuous external clock (ECLK). The ECLK frequency is a user-programmable ratio of the peripheral

interface clock (VCLK) frequency.

An error signaling module (ESM) provides a common location within the device for error reporting allowing

efficient error checking and identification.
