6. Further Information
The following references may be found useful when using the adapter:
Philips Semiconductors Technical Handbook Book 4 Parts 12a and 12b. These give details of the
I2C compatible ICs, and the I
2 C Bus specification. The PCF8584P used on the adapter is
included in later editions. Where the data sheet and this manual disagree, this manual should
always be followed when using the adapter.
Philips Components Data Sheet for PCF8584
Philips Application Note No EIE/AN90001 - Interfacing PCF8584 I 2 C bus controller to 80(C) 51
family micro controllers. This gives some useful code but is not written directly for the PC. Please
note - the hardware information on the PCF8584 given in this application note sometimes
contradicts the data sheet referenced in 8.2, in
general the data sheet is correct; the only
exception is that a Stop should be sent as c3 (Hex) - as shown in the application, not 43 (hex) -
implied in the data sheet ) see Appendix B of this manual for details of control codes). Where in
doubt, follow this manual.
