142 / 163 page ![]() Philips Semiconductors Product Specification Rev. 3.0; May 2003 Multiple Protocol Contactless Reader IC CL RC632 142 Confidential 21 TEST SIGNALS 21.1 General The CL RC632 allows different kind of signal measurements. These measurements can be used to check the internally generated and received signals using the possibilities of the serial signal switch as described in chapter 15. Furthermore, with the CL RC632 the user may select internal analogue signals to measure them at pin AUX and internal digital signals to observe them on pin MFOUT by register selections. These measurements can be helpful during the design-in phase to optimise the receiver’s behaviour or for test purpose. 21.2 Measurements Using the Serial Signal Switch Using the serial signal switch at pin MFOUT the user may observe data send to the card or data received from the card. The following tables give an overview of the different signals available.
