Timing parameters are at the default output drive strength (half drive strength).
t
Applies to ADV# controlled Asynchronous Read operations.
Applies when control signals (ADV#, CS#, UB#/LB#) are active.
When operating the PSRAM as an ADMux I/O interface, Page-Mode operation is not available.
CSL
max limit applies during asynchronous reads when page mode is enabled.
