使用16DIO的xml文件,不需要mcu来设计PDO/SDO的协议栈;利用该模式的DO表示FPGA寄存器,DI表示数值;[ 关于该PDI接口,AX58100手册有说明The Process Data Interface (PDI, also name host interface) provides SPI slave, asynchronous 8/16-bitmicrocontroller interface (also name Asynchronous Local Bus) and Digital I/O. The SPI slave and asynchronous8/16-bit Local Bus interface will be used when external MCU in employed the slave system, and the Digital I/O isused for when direct I/O control.]
关于16DIO.XML文件中地址与索引的对应关系,可能是芯片内固定好的.[The AX58100 supports function register mirror from/to ESC memory space, the mirror registers located at processdata memory address from 0x3000 to 0x33FF]
