DS90UB964-Q1: no lock, no line count, no line length after 964 initialization

Part Number: DS90UB964-Q1

Dear team,

My customer's application is 964 paired with 933. When testing, we only connect one camera module to the 964. After initialization, the lock is always low(0x4D), and registers 0x73/74/75/76 are all 0. In addition, 0x4E is also abnormal. Could you please help review the initial code and analyze the potential reasons? Thank you!

The initialization code is as below,

0x01 0x01

0x1F 0x00

0x4C 0x01

0x58 0x58

0x70 0x1E

0x5C 0xB0

0x4C 0x12

0x70 0x5E

0x5C 0xB2

0x4C 0x24

0x70 0x9E

0x5C 0xC0

0x4C 0x38

0x70 0xDE

0x5C 0xC2

0x4C 0x0F

0x58 0x58

0x7C 0xC0   

0x6D 0x7F

0xB0 0x1C

0xB1 0x13

0xB2 0x1F

0x32 0x01

0x21 0x03

0x20 0x00

Read register after initialization,
