  • Port Output Enable (GPT) block

Libraries:
Embedded Coder Support Package for Renesas RA Microcontrollers / Renesas RA6 Based

Description

The Port Output Enable (GPT) block implements Port Output Enable (POEG) functionality for General Purpose Timer (GPT) PWM modules on Renesas RA microcontrollers. The POEG mechanism provides hardware protection and software control of PWM outputs.

Use this block to:

  • Enable PWM outputs by resetting the POEG state through software.

  • Disable PWM outputs by issuing a POEG stop request.

  • Monitor the POEG event state to detect active disable conditions.

  • Retrieve FSP (Flexible Software Package) API status information for error diagnostics.

The block accepts logical input signals and outputs status information as uint32 values when you enable the corresponding ports. This functionality enables you to manage PWM outputs in Renesas RA–based applications.

Note

The Port Output Enable (GPT) block may execute before the corresponding PWM block, depending on the model execution order. This behavior ensures that POEG protection is active before PWM output starts. If a POEG trigger is active during initialization, PWM outputs can remain disabled until the POEG state is cleared

Examples

Control PWM Output Using POEG Triggers on Renesas RA Microcontrollers

Control PWM Output Using POEG Triggers on Renesas RA Microcontrollers

Use the POEG (Port Output Enable for GPT) feature in the Embedded Coder® Support Package for Renesas® RA Microcontrollers to control PWM output using both software and hardware triggers.

Ports

Input

expand all

Logical signal that resets the POEG state to enable PWM output after a disable event.

  • 1 (true) — Enable PWM output.

  • 0 (false) — No action.

Dependencies

To enable this port, select the Enable input to start PWM parameter.

Data Types: Boolean

Logical signal that disables PWM output using the POEG mechanism.

  • 1 (true) — Disable PWM output.

  • 0 (false) — No action.

Dependencies

To enable this port, select the Enable input to stop PWM parameter.

Data Types: Boolean

Output

expand all

Outputs the current POEG event state as a uint32. The value indicates whether a disable request is active.

  • 0 — No disable request is active (PWM output is enabled).

  • 8 — Software stop request is active.

  • 65537 — Pin state triggered disable is active.

  • Nonzero (other values) — Disable request is active. Value indicates the specific POEG event state.

Note

The State output reports encoded POEG status information. Values such as 0, 8, and 65537 correspond to software-stop and pin-state conditions.

Dependencies

To enable this port, select the Output POEG state parameter.

Data Types: uint32

Outputs the status of the underlying FSP API operation as a uint32.

  • 0 — Operation completed successfully.

  • Nonzero — An error occurred during the API operation. Value represents the FSP error code.

Dependencies

To enable this port, select the Output FSP status parameter.

Data Types: uint32
