Notes:
1. X means "Don't Care".
2. All inputs in this table must beet setup and hold time around the rising edge of CLK.
POWER UP SEQUENCE
Vddq → Vdd¹ → I/O Pins²
Notes:
1. Vdd can be applied at the same time as Vddq
2. Applying I/O inputs is recommended after Vddq is ready. The inputs of the I/O pins can be applied at the
same time as Vddq provided Vih (level of I/O pins) is lower than Vddq.
