DS90UB954-Q1: BC_GPIO_CTL0 / BC_GPIO_CTL1 Register

Guru 29720 points
Part Number: DS90UB954-Q1


Hi Team,

I understood BC_GPIO_CTL0 / BC_GPIO_CTL1 Register determines assignment for back channel GPIO0-4.
I would like to ask two questions as the following.

1)
Should we set BC_GPIO1_SEL[7:4]=0000 if we wants to assign GPIO0 of DS90UB954 (Deserializer) to GPIO1 of DS90UB953 (Serializer)?



2)
What is occured if we set BC_GPIO1_SEL[7:4]=0111?
I would like to ask because DS90UB954 has GPIO0-GPIO6 and doesn't have GPIO7.

Best Regards,
