给MOTO 360 单片机 开发的MODBUS协议 直流奥特寻协议。。要用SDS编译

/************************************************************************
	Example specification file for the 68000 family.  This example
	assumes ROM is at address 0x0000 and RAM is at address 0xC000.
	Region "data" (which contains initialized RAM variables) must
	be linked into RAM to give the variables their correct addresses,
	but will be downloaded into ROM at location DATA using downloader
	option "-m data,DATA".  Startup code will copy it from location
	DATA back into RAM.
