External Bus and Calibration bus timing specified at fSYS = 150 MHz and 100 MHz, VDD = 1.14 V to 1.32 V,

VDDE = 3 V to 3.6 V (unless stated otherwise), TA =TL to TH, and CL = 30 pF with DSC = 0b10.

The external bus is limited to half the speed of the internal bus. 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.

Refer to Fast Pad timing in Table 35 and Table 36 (different values for 1.8 V vs. 3.3 V).

Measured at 50% of ALE.

When CAL_TS pad is used for CAL_ALE function the hold time is 1 ns instead of 1.5 ns.
