CY7C68013A - RESERVED pin
What should be done with the RESERVED pin #21 of 56-pin CY7C68013A?
The RESERVED pin (#21) of the 56pin CY7C68013A device is used for internal testing and verification, and should be connected to GND in the design. Similarly, the RESERVED pin of both 128-pin CY7C68013A and 100-pin CY7C68013A devices also should be connected to GND.
