Embedded Target for Motorola MPC555

Description

The MIOS Digital Out (MPWMSM) block is a device driver that lets you use the MIOS Pulse Width Modulation Submodule (MPWMSM) in digital output mode. In digital output mode, the Pulse Width Modulation (PWM) feature of the MPWMSM is turned off. When the input signal is greater than zero, a logical 1 is written to the output pin; otherwise a logical zero is written.

Refer to section 15.12, "MIOS Pulse Width Modulation Submodule (MPWMSM)," in the MPC555 Users Manual for further information on the parameters described below.

Dialog Box

MPWM submodule number

Selects a PWM submodule for output.

Sample time

Sample time of the block.

Invert output polarity

Switches the output level for logic one and zero.

Enable pass through (show simulation input)

Lets you provide a signal from this block for use in simulation. When this option is enabled, an outport appears on the block. The block input is passed through to the output during simulation. (See Data Type Support and Scaling for Device Driver Blocks for information on supported input/output data types and scaling of input/output signals.) This option affects simulation only.
