DS90UB936-Q1: 关于DS90UB936的几个寄存器的理解的问题

Part Number: DS90UB936-Q1

您好TI,我有如下问题:

1.
寄存器PORT_ISR_LO(Address 0xDB)的bit IS_LINE_CNT_CHG(bit 5)被置为1时,是表示FPD-link上传输过来的视频画面分辨率的高度发生变化了吗?

2.
当寄存器RX_PORT_STS1(Address 0x4D)的值为0x01时,bit PORT_PASS(bit 1)为0,0表示“Receive input does not meet PASS criteria”,这是表示FPD-link上传输过来的视频有问题吗?还是说视频之外的数据有问题?还是表明没有视频数据?
