Dear Sir/Madam,


We are going to use the parallel byte interface mode,and have two questions about DB[13:9].


Q1.There is the following description.   P.15 of datasheet,

    "When PAR/SER/BYTE SEL = 1, these pins should be tied to AGND"


    In the case of the split plane,we think that these pins should be tied to digital ground planes.

    Which connection is the best or the better?.


Q2. Is there any problem in no connecting(floating)?.


Thank you.


Sincerely yours,
