[ DS90UB914A-Q1 ] Behavior of LOCK bit (0x1C[0], General Status Register)
Hi,
My customer has shared a bit strange behavior of LOCK bit (0x1C[0]).
Can you take a look and comment on it?
When a camera cable(FPD-Link III cable) is disconnected from a receiver board (DS90UB914A-Q1 mounted), and their processsor attempts to read 0x1C, general status register, the initial read out indicate that the LOCK bit (bit[0]) is "0".
However, they repeat read out multiple times, LOCK bit turn to be "1", even though the cable is still disconnected.
According to the information from reference posts below, this bit should indicate lock status dynamilcally.
Thank you for your support in advance.
Regards,
Ken
