16 / 163 page ![]() Philips Semiconductors Product Specification Rev. 3.0; May 2003 Multiple Protocol Contactless Reader IC CL RC632 16 Confidential 4.3.3 COMMON READ/WRITE STROBE AND HAND-SHAKE MECHANISM: EPP For timing specification refer to chapter 22.5.2.3. Remarks for EPP: Although in the standard for the EPP no chip select signal is defined, the N_CS of the CL RC632 allows inhibiting the nDStrb signal. If not used, it shall be connected to DVSS. After each Power-On or Hard Reset the nWait signal (delivered at pin A0) is high impedance. nWait will be defined at the first negative edge applied to nAStrb after the Reset Phase. The CL RC632 does not support Read Address Cycle. CL RC632 NCS A2 A1 A0 D0...D7 ALE NRD NWR Multiplexed Address/Data (AD1...AD8) Address Strobe (nAStrb) HIGH HIGH nWait Read/Write (nWrite) Data Strobe (nDStrb) LOW Figure 4-3: Connection to µ-Processors with Common Read/Write Strobes and Hand-Shake |
