LL_SWPMI_Activate()

__STATIC_INLINE void LL_SWPMI_Activate

(

SWPMI_TypeDef *

SWPMIx

)

Activate Single wire protocol bus (SUSPENDED or ACTIVATED state)

SWP bus stays in the ACTIVATED state as long as there is a communication with the slave, either in transmission or in reception. The SWP bus switches back to the SUSPENDED state as soon as there is no more transmission or reception activity, after 7 idle bits. @rmtoll CR SWPACT LL_SWPMI_Activate

Parameters

SWPMIx

SWPMI Instance

Return values

None
