Hello,
I want to interface two sensor on one bus line by SPC protocol, So i will use single pin as input and output. So how should be the declaration of pin as input or output (in manual it is written as quasi bidirection )
And how should i generate the trigger pulse for selection of one sensor according to address.
Can any one please help in this regards
Thanks

Hello,
the pin must be set to corresponding alternate output (SPC) with open drain. External pull up is needed. Trigger pulses can be generated by write to SENT_SCRx register. See chapter SPC Operation for more Information in the device user manual.
