DS90UB940N-Q1: Change CSI Port via Register

Part Number: DS90UB940N-Q1

Hi.

I've got the wrong voltage divider on the MODE_SEL1 pin on my prototype board, selecting CSI0 as output instead of CSI1. Before I break out the soldering iron, is there a way to change this via registers? I've tried setting the indirect registers CSI_EN_PORT0 and CSI_EN_PORT1 to 0x00 and 0x37 respectively, but that does not seem to have any effect. Am I missing some step?

Sincerely.

Alex
