/*有关BL7442ic卡的函数，包括：
Delay(uchar j)延时函数、ic_start()开始条件函数、ic_stop()停止条件函数、clock()时针函数
out_byte(uchar byte) sends 8 bit 'byte' to the BL7442
read_data() reads 8 bits from the sle4442 & stores value in 'rd_data'
ic_break() 复位停止函数
ISO_no_read() reads 32 bit ISO stasndard response to reset
rd_main_ram(uchar read_start_addr)读主存储区函数
proc_mode_chek() ic_card 在处理模式时进行监测是否处理完毕，最大延时255个时钟
