(16) Chip Select Output Timing
(VCC
= 2.7 V to 3.6 V, VSS = 0.0 V, TA = 40 °C to +85 °C)
* : tCP : See “ (1) Clock Timing Standards”.
Note : Due to the configuration of the internal bus, changes in the chip select output signal are clock synchronous
and therefore may causes bus conflict conditions. AC cannot be warranted between the ALE output signal
and the chip select output signal.
