15 0 Switching Characteristics
Note 1 Cycles T1 T2 T3 and T4 are only issued for the first transfer in a burst when 32-bit mode has been selected
Note 2 The rate of bus clock must be high enough to support transfers to from the FIFO at a rate greater than the serial network transfers from to the FIFO
Note 3 These limits include the RC delay inherent in our test method These signals typically turn off within 15 ns enabling other devices to drive these lines with
no contention
