使用的是处理器是F2812，编译环境是CCS3.3，
Uint16 dumpdata;
GpioDataRegs.GPFCLEAR.bit.GPIOF10 = 1;
asm(" RPT #40 || NOP ");
McbspaRegs.DXR1.all = MCP_0|MCP_IOCON;
while(!McbspaRegs.SPCR1.bit.RRDY);
dumpdata = McbspaRegs.DRR1.all;
代码中明明有使用dumpdata，编译时却提醒 warning: variable "dumpdata" was set but never used，这是什么原因？
不吝赐教
