* Description: sst89e554-Firmware for RC500 Serial Reader
*
*****************************************************************************
*
* Version | Date | PCB | Description
* --------+----------+-------+------------------------------------------------
*3600v0.1 | 22/04/03 | | weigand ,RS485, IAP
* V140 | 08/04/04 | | Adding 15693 funtions
* V130 | 08/02/03 | | Adding some funtions about SAM
* V120 | 20/01/03 | | Modify reader.h,adding rc500cmd.h
* V110 | 15/01/03 | | reset pin control by FIFO out pins.Adding two new command
* | | | (READ EEPROM C6 and WRITE EEPROM C7).
* | | | delay using a fixed time,not "for loop".
* | | | New routine "funtions()" is generated in funtion.
* V100 | 25/12/02 | | Initial version,TypeA and TypeB
