MPL PATI Digital Output

MPL PATI Digital Output block (not recommended)


Simulink® Real-Time™ Library of Drivers No Longer Recommended for Use.

To open this library, type xpcobsoletelib in the Command Window.

General Description

The individual bits of the MPL PATI digital output are in different registers. As a result, you cannot update multiple digital outputs at the same time. Use a separate MPL PATI Digital Output block to control each bit.


To execute a model using this block, you must first write MPL boot code on the EEPROM using the MPL PATI EEPROM Write block. To flash the EEPROM with the boot code, add the EEPROM Write block to an empty model, then build and execute that model. You can then execute the actual model. See MPL PATI EEPROM Write block for further information.

Block Parameters


From the list, select from 1 to 32. This is the single TPU channel that this block controls.

Channel priority

From the list, select Low, Medium, or High priority. This changes the order that individual timers are serviced. See the MPC555 TPU documentation for more information.


This parameter controls the behavior of the bit at model termination. Enter one of the following values:

  • 1

    Resets the output bit to the value in Initial Value.

  • 0

    Leaves the output bit at the most recent value attained while the model was running.

Initial value

Enter the initial voltage value for the output bit. The output bit is set to this value between the time the model is downloaded and the time the model is started. Also, if the Reset parameter has a value of 1, the output bit is reset to the initial value when the model is stopped.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

PCI slot

If only one board of this type is in the target computer, enter -1 to locate the board.

If two or more boards of this type are in the target computer, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber,SlotNumber]. To determine the bus number and the PCI slot number, type:

tg = slrt;
getPCIInfo(tg, 'installed')
