,commodore ~ aamlcanduct;ar graup [t\!][K!A]@~ MPS 6529 SINGLE-PORT INTERFACE 6529 SINGLE PORT INTERFACE DESCRIPTION The 6529 is a static microprocessor compatible, 8-bit I/O Port with passive output pull-up devices.
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.
It is recommended that the 6529 be interfaced to open collector output type devices.
