(example: length of symbol2 = 5, bit7 and bit6 are ignored, bit5 to bit0 define th e symbol pattern, bit5 is sent first) which symbol-pattern is sent can be confi gured in the txframecon register. symbol0, symbol1 and symbol2 can be sent before da ta packets, symbol1, symbol2 and symbol3 can be sent after data packets. each symbol is defined by a set of registers. symbols are configured by a pair of registers. symbol0 and symbol1 share the same configuration and symbol2 and symbol3 share the same configur ation. the configuration includes setting of bit-clock- and subcarrier-frequency, as well as selection of the pulse type/length and the envelope type. 8.7 memory 8.7.1 memory overview the mfrc630 implements th ree different memo ries: eeprom, fifo and registers. at startup, the initializatio n of the registers which defin e the behavior of the ic is performed by an automatic copy of an eeprom area (read/write eeprom section1 and section2, register reset) into the registers. the behavior of the mfrc630 can be changed by executing the command loadprotocol, which copies a selected default protocol from the eeprom (read only eeprom section4, register set protocol area) into the registers. the read/write eeprom se ction2 can be used to store any user data or predefined register settings. these predefined se ttings can be copied with the command "loadregister" into the internal registers. the fifo is used as input/out buffer and is able to improve the performance of a system with limited interface speed.

(lpcd_i_ result, lpcd_q_result).this time period can be handled with timer3. the value is compar ed with the min/max values in the registers (lpcd_imin, lpcd_imax; lpcd_qmin, lpcd_qma x). if it exceeds the limits, a lpcdirq is raised. after the command lpcd the standby of the mfrc630 is activated, if selected. the wake-up timer4 can activate the system after a given time. for the lpcd it is recommended to set t4autowakeup and t4autorestart, to start the timer and then go to standby. if a card is detected the timer stop s and the communication can be started. if t4autowakeup is not set, the ic will not enter st andby mode in case no card is detected. 8.9.4 reset and start-up time a 10 ? s constant high level at the pdown pin starts the internal reset procedure. the following figure shows the internal voltage regulator: this internal procedure consists of two phases: ? power on reset ? startup time when the mfrc630 has finished this two phases the reader ic is in full mode and is ready to be used. refer to section 13.1 ? timing characteristics ? fig 28. internal pdown to voltage regulator logic 001aan360 pvdd pdown v ss glitch filter internal voltage regulator v dd v ss 1.8 v 1.8 v avdd dvdd
