I want to confirm a recommendation about TEST_MODE pin.
According to the check List and HW Design Guide, there is a following recommendation about TEST_MODE pin.
So user must float it or connect GND directly.
The TEST_MODE input is internally connected to an on-chip pulldown device. The user must either float this signal or tie it to GND.
On the other hand, SABRE isn't following the recommendation.
It connect GND through 4.7 Kohm in SPF-27616_C5.pdf.
What is freescale's recommendation ?
Please also tell me why does SABRE board not follow the recommendation.
