* THM3060<---SPI----->MCU<-----UART+I2C------->SAM
*
* THM3060 is RF adapter which support ISO/IEC14443 A/B ,ISO/IEC15693 
* SAM is ID2 card security module
*
* Interface between THM3060 and MCU is SPI
* Interface between SAM and MCU are I2C and UART
* Interface between HOST and MCU is UART
*
* For MCU STC15F2K08S2 based application:
*     SPI and I2C is gpio simulated.
*     UART1 is for HOST&MCU
*     UART2 is for SAM&MCU
