Data is written to the port when CS and RNI/ are low. Data is read from the port when CS is low and RNI/ is high. The passive output pull-ups allow a single bit to act as either an input or an output without I/O mode switching. This device is provided with special circuitry to provide power-on reset. Under normal fast poweron conditions the outputs will initialize in the input high impedance state. With very slow or noisy power-up, there is some possibility the device will initialize with putputs driven low.
