Hi, when comparing the ADSP-21489 Ez-Kit Schematic to the pinout provided for the 176-Lead LQFP_EP Package ADSP-21489 in page 61 of the datasheet, I notice there is a discrepancy in how pins 137, 139, 142, 140, and 145 are labled.
In the Ez-Kit Schematic they are marked as NC, and are connected to flags relating to MLB. There is an optional jumper to connect them to ground and the schematic says MLB is not supported on the 176-Lead package.
In the datasheet these pins are marked as GND.
Which are they actually. What is MLB? I am making a board layout and need to know how to properly connect these pins.
