Note to Table 16:
(1) To meet the IOL and IOH specifications, you must set the current strength settings accordingly. For example, to meet the SSTL15CI specification (8 mA), you
should set the current strength settings to 8 mA. Setting at lower current strength may not meet the IOL and IOH specifications in the handbook.

Note to Table 17:
(1) The maximum value for VSWING(DC) is not defined. However, each single-ended signal needs to be within the respective single-ended limits
(VIH(DC) and VIL(DC)).
