Function Documentation

__STATIC_INLINE void LL_SWPMI_Activate ( SWPMI_TypeDef *  SWPMIx )

Activate Single wire protocol bus (SUSPENDED or ACTIVATED state)

Note:
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. CR SWPACT LL_SWPMI_Activate
Parameters:
SWPMIxSWPMI Instance
Return values:
None

Definition at line 310 of file stm32l4xx_ll_swpmi.h.
