Award-Winning Development Environment
A key application-specific feature of the 56F8146 is the inclusion of one Pulse Width Modulator (PWM)
module. This module incorporates three complementary, individually programmable PWM signal output
pairs and can also support six independent PWM functions to enhance motor control functionality.
Complementary operation permits programmable dead time insertion, distortion correction via current
sensing by software, and separate top and bottom output polarity control. The up-counter value is
programmable to support a continuously variable PWM frequency. Edge-aligned and center-aligned
synchronous pulse width control (0% to 100% modulation) is supported. The device is capable of
controlling most motor types: ACIM (AC Induction Motors); both BDC and BLDC (Brush and Brushless
DC motors); SRM and VRM (Switched and Variable Reluctance Motors); and stepper motors. The PWM
incorporates fault protection and cycle-by-cycle current limiting with sufficient output drive capability to
directly drive standard optoisolators. A “smoke-inhibit”, write-once protection feature for key parameters
is also included. A patented PWM waveform distortion correction circuit is also provided. Each PWM is
double-buffered and includes interrupt controls to permit integral reload rates to be programmable from 1
to 16. The PWM module provides reference outputs to synchronize the Analog-to-Digital Converters
through two channels of Quad Timer C.
The 56F8146 incorporates a Quadrature Decoder capable of capturing all four transitions on the two-phase
inputs, permitting generation of a number proportional to actual position. Speed computation capabilities
accommodate both fast- and slow-moving shafts. An integrated watchdog timer in the Quadrature Decoder
can be programmed with a time-out value to alert when no shaft motion is detected. Each input is filtered
to ensure only true transitions are recorded.
This controller also provides a full set of standard programmable peripherals that include two Serial
Communications Interfaces (SCIs); two Serial Peripheral Interfaces (SPIs); and two Quad Timers. Any of
these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. An
internal interrupt controller is also a part of the 56F8146.
1.3 Award-Winning Development Environment
TM
Processor Expert
(PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use
component-based software application creation with an expert knowledge system.
The CodeWarrior Integrated Development Environment is a sophisticated tool for code navigation,
compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards
will support concurrent engineering. Together, PE, CodeWarrior and EVMs create a complete, scalable
tools solution for easy, fast, and efficient development.

Figure 1-1
illustrates how the
56800E system buses communicate with internal memories, the external memory interface and the IPBus
Bridge.
Table 1-2
lists the internal buses in the 56800E architecture and provides a brief description of
their function.
Figure 1-2
shows the peripherals and control blocks connected to the IPBus Bridge. The
figures do not show the on-board regulator and power and ground signals. They also do not show the
multiplexing between peripherals or the dedicated GPIOs. Please see
