ADV7619 Interrupt Question

Question in Reference to UG-237 Rev. C page 176

 

According to this doc the HDMI interrupts in Group 3 (Table 75) are valid under the following conditions:

  • ADV7619 is configured in HMDI mode
  • TMDS_CLK_A_RAW is set to 1 if Port A is the active HDMI port
  • TMDS_CLK_B_RAW is set to 1 if Port B is the active HDMI port
  • TMDSPLL_LCK_A_RAW is set to 1

 

 

I'm only using Port B so TMDSPLL_LCK_A_RAW will never be set to 1. That condition implies these interrupts can only be used with Port A, which doesn't seem to make sense.  Should the doc really read:

 

TMDSPLL_LCK_A_RAW is set to 1 if Port A is the active HDMI port

TMDSPLL_LCK_B_RAW is set to 1 if Port B is the active HDMI port

 

I'm asking because I'm having trouble getting NEW_TMDS_FRQ interrupts, one of the interrupts in Table 75.
