I want to achieve the function of the following block diagram. I can set the input and output of any port, but I can't achieve simultaneous input and output of two cameras. I also don't know how to perform simultaneous through of two IIC and GPIO. Could you provide me with a large block diagram of the drivers for DS90UB9702 and DS90UB971 or an example for me to test myself?
for example:

This is one of my single-channel configurations
REG=0x7a,0x0c,0x04 REG=0x7a,0xe4,0x00 REG=0x7a,0x01,0x21 REG=0x7a,0x4c,0x24 DELAY=100 REG=0x7a,0x58,0x5e REG=0x7a,0xA0,0x00 REG=0x7a,0x5c,0x30 REG=0x7a,0x5d,0x36 REG=0x7a,0x65,0x36 REG=0x7a,0xb0,0x04 REG=0x7a,0x1f,0x00 REG=0x7a,0xc9,0x1e REG=0x7a,0xb0,0x1c REG=0x7a,0xb1,0x92 REG=0x7a,0xb2,0x40 REG=0x7a,0x32,0x12 REG=0x7a,0x33,0x03 REG=0x7a,0x20,0x04
