1 EBI timing specified at VDD = 1.35V to 1.65V, VDDE = 1.6V to 3.6V (unless stated otherwise), VDD33 and VDDSYN = 3.0V

to 3.6V, TA = TL to TH, and CL = 30pF with DSC = 0b10.

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

3 Refer to Fast Pad timing in Table 17 and Table 18 (different values for 1.8V vs 3.3V).

4 Internal Arbitration

5 External Arbitration

6 The EBTS=0 timings are only valid/ tested at VDDE=2.25-3.6V, whereas EBTS=1 timings are valid/tested at 1.6–3.6V.
