pinout ADSP-21489

Hi,

 

While taking a close look at the 21489 datasheet and comparing the pinout to that seen in the EZ Board, we see that certain pins defined as no-connect and "MLB" say that they are ground on the datasheet.

 

For example, pins 137, 139, 140, 142, 145 all say GND on the datasheet, but are routed to an "MLB" connector on the EZ board.

(p60-61 of http://www.analog.com/static/imported-files/data_sheets/ADSP-21483_21486_21487_21488_21489.pdf)

 

Could you please clarify how these pins should be handle on a customer board?

 

Thank you,

Marc
