The maximum external bus frequency is 66 MHz for 16-bit muxed mode and 33 MHz for non-muxed mode. For The EBI division factor should be set accordingly based on the internal frequency being used. 3 Refer to Fast Pad timing in Table 35 and Table 36 (different values for 1.8 V vs. 3.3 V). 4 Measured at 50% of ALE. 5 When CAL_TS pad is used for CAL_ALE function the hold time is 1 ns instead of 1.5 ns.
