Product data sheet PUBLIC Rev. 3.3 — 6 July 2010 057433 13 of 115 NXP Semiconductors MFRC530 ISO/IEC 14443 A Reader IC 9.2.1 Product information field (read only) [1] Byte 4 contains the current version number. 9.2.2 Register initialization files (read/write) Register initialization from address 10h to address 2Fh is performed automatically during the initializing phase (see Section 9.7.3 on page 27) using the StartUp register initialization file. In addition, the MFRC530 registers can be initialized using values from the register initialization file when the LoadConfig command is executed (see Section 11.4.1 on page 84). Remark: The following points apply to initialization: • the Page register (addressed using 10h, 18h, 20h, 28h) is skipped and not initialized. • PreSetxx registers: do not change. • all reserved register bits set to logic 0: do not change. 9.2.2.1 StartUp register initialization file (read/write) The EEPROM memory block address 1 and 2 contents are used to automatically set the register subaddresses 10h to 2Fh during the initialization phase. The default values stored in the EEPROM during production are shown in Section 9.2.2.2 “Factory default StartUp register initialization file”. Table 12.
