We use AD9398 with external HDCP key.
But HDCP authentification is not completed.
(Astro VG-849C -----> AD9398)
It seems that KSV of Rx is read correctly, but R0 of Rx = "0000" and register 0x2F = 67h(HDCP Keys Read=0).
(Refer to attached file)
Should we set any register for enabling external HDCP key?
And would you please tell us advice for solving this issue?
