8.3.6 Pwm_GetOutputState [SWS_Pwm_00100] Definition of API function Pwm_GetOutputState ⌈ Service Name Pwm_GetOutputState Syntax Pwm_OutputStateType Pwm_GetOutputState ( Pwm_ChannelType ChannelNumber ) Service ID [hex] 0x05 Sync/Async Synchronous Reentrancy Reentrant for different channel numbers Parameters (in) ChannelNumber Numeric identifier of the PWM ▽ △ Parameters (inout) None Parameters (out) None Return value Pwm_OutputStateType PWM_HIGH The PWM output state is high PWM_LOW The PWM output state is low Description Service to read the internal state of the PWM output signal. Available via Pwm.h ⌋ [SWS_Pwm_00022] Upstream requirements: SRS_Pwm_12385 ⌈The function Pwm_GetOutputState shall read the internal state of the PWM output signal and return it as defined in the diagram below. Regarding error detection, the requirements [SWS_Pwm_00117], [SWS_Pwm_00047], [SWS_Pwm_10051] and [SWS_Pwm_20051] are applicable to the function Pwm_GetOutputState.⌋ [SWS_Pwm_10085] Upstream requirements: SRS_BSW_00171 ⌈The function Pwm_GetOutputState shall be pre compile time configurable On/Off using the configuration parameter: PwmGetOutputState.⌋ [SWS_Pwm_20085] Upstream requirements: SRS_BSW_00171 ⌈The function Pwm_GetOutputState shall be configurable On/Off by the configuration parameter: PwmGetOutputState {PWM_GET_OUTPUT_STATE_API}. Due to real time constraint and setting of the PWM channel (project dependant), the output state can be modified just after the call of the service Pwm_GetOutputState.⌋ [SWS_Pwm_30051] Upstream requirements: SRS_BSW_00323, SRS_BSW_00386 ⌈If Pwm_GetOutputState is called before module initialization, or with an invalid channel, it shall return PWM_LOW.⌋
