Note:
1. The min VILand max VIH values are based on the min and max OVIN respective values found in Table 3.
2. The symbol OVIN represents the input voltage of the supply. It is referenced in Table 3.

Notes:
1. GPIO inputs and outputs are asynchronous to any visible clock. GPIO outputs must be synchronized before use by any
external synchronous logic. GPIO inputs are required to be valid for at least tPIWID to ensure proper operation.
