DS90UH949-Q1: HDCP_ENC_EN

Part Number: DS90UH949-Q1

Hi team,

1. After Authentication completed (AUTHED=1), I set HDCP_ENC_EN=1.

2. I read HDCP_STS register AUTHED bit = 0

3. Repeat reading HDCP_STS register AUTHED bit = 1.

Question : AUTHED bit will be cleared to 0 when I set HDCP_ENC_EN and return to 1 automatically?

regards,

  • Hello,

    The AUTHED bit will be cleared if authentication is lost or if the controller restarts authentication. If you also reset HDCP_EN in the command to set HDCP_ENC_EN, authorization will be restarted, which would cause AUTHED to go to 0 then 1 again.

    Regards,

    Ben
