DS90UB964-Q1: How to read ub964 camera status

Hello Xueze,

you need to read register 0x4D[0] for each enabled Rx Port.

Alternative is to activate the function "Logical AND of Lock indication from enabled RX ports" into any GPIO pin, and connect that pin into your SoC or uC.

Hello xxz,

for reading LOCK for Port0 you need to :

Write 0x4C = 0x01

Read 0x4D

To read LOCK for Port1 you need to :

Write 0x4C = 0x12

Read 0x4D

To read LOCK for Port2 you need to :

Write 0x4C = 0x24

Read 0x4D

To read LOCK for Port3 you need to :

Write 0x4C = 0x38

Read 0x4D
