State of the RXSC/D* signal while VLTN is asserted for the CY7C9689A

Question: What is the state of the RXSC/D* signal while VLTN is asserted for the CY7C9689A?

 

Answer:

RXSC/D* will remain unchanged when VLTN is asserted.
In the pin description of VLTN on page 7 of the datasheet, it states that "When VLTN is asserted the values on the output DATA and COMMAND buses remain unchanged" and as RXSC/D* comes from the same output buffer as the DATA and COMMAND buses it behaves the same.
