SignalDataObject

HWO_UART

Hardware Out interface for UART.
No Signal-Datatype will be defined so that a typedef will be generated into the signal configuration.
Pointer access is granted so signal memory can be used directly by the application.

Warnings

RTE (1)

RTE Warnings for SignalDataObject HWO_UART
RTE warnings are related to the configured behaviour of the RTE.

HWO_UART allows pointer access to its payload.
