ADV7441A external clock input XTAL

XTAL Input: I will not be using a crystal but a external 3.3 V 28.63636 MHz clock oscillator source.

 

In the "Hardware Database Manual" (ADV7441A_HW_RevJ.pdf)

3.1.5 Xtal Clock Input Pin Functionality
     XTAL_TTL_SEL, User Map, Address 0x13, [2]
     If XTAL_TTL_SEL is set to 1, a different input buffer can be selected, which slices at TTL
     compatible levels. This inhibits operation of the crystal oscillator and, therefore, can only be used
     when a clock signal is applied.

 

However, in the "SOFTWARE MANUAL" (ADV7441A_SW_RevD.pdf), there is no bit listed at Address 0x13, [2].

Which is correct?
