Embedded Target for Motorola MPC555

The Embedded Target for Motorola MPC555 Block Libraries

The Embedded Target for Motorola MPC555 provides three block libraries:

• The Embedded Target for Motorola MPC555 library (mpc555drivers.mdl) provides device driver blocks that let your applications access on-chip resources. The I/O blocks support the following features of the MPC555:
• Pulse width modulation (PWM) generation or digital output via the Modular Input/Output Subsystem (MIOS) PWM unit.
• Analog input via the Queued Analog-to-Digital Converter (QADC64).
• Digital input and output via the MIOS.
• Digital input via the QADC
• Frequency and pulse width measurement via the MIOS Double Action Submodule (MDASM).
• Transmission or reception of Controller Area Network (CAN) messages via the MPC555 TouCAN modules.
• The CAN Message Blocks library (canblks.mdl) provides device driver and utility blocks that support the Controller Area Network (CAN) protocol. CAN is an industry standard protocol used in automotive electronics and many other embedded environments where dispersed components require sharing of information. The CAN Message Blocks library includes blocks for transmitting, receiving, decoding, and formatting CAN messages. The CAN Message Blocks library also supports message specification via the Vector-Informatik CANdb standard.
• The CAN Drivers (Vector) library (vector_candrivers.mdl) provides blocks for configuring and connecting to Vector-Informatik CAN hardware and drivers.

The following sections provide complete information on each block in the Embedded Target for Motorola MPC555 block libraries, in a structured format. Refer to these pages when you need details about a specific block. Click Help on the Block Parameters dialog for the block, or access the block reference page through Help.

Using Block Reference Pages

Block reference pages are listed in alphabetical order by the block name. Each entry contains the following information:

• Purpose -- describes why you use the block or function.
• Library -- identifies the block library where you find the block.
• Description -- describes what the block does.
• Dialog Box -- shows the block parameters dialog and describes the parameters and options contained in the dialog. Each parameter or option appears with the appropriate choices and effects.
• Examples -- optional section that provides demonstration models to highlight block features.

In addition, block reference pages provide pictures of the Simulink model icon for the blocks.
