The previous equation accounts for the input limitations, but you must
apply the appropriate equation from
limitations.
When at least one additional output exists but no voltage referenced
inputs exist, apply the appropriate formula from
When additional voltage referenced inputs and other outputs exist in the
same VREF bank, then the bidirectional pad limitation must again
simultaneously adhere to the input and output limitations. See the
following equation.
<Total number of bidirectional pads> + <Total number of input pads> 40 (20 on
each side of the VREF pad)
