在用CCS3.3编译程序时出现如下错误：
error: this declaration has no storage class or type specifier
error: declaration is incompatible with "volatile struct PIE_CTRL_REGS PieCtrl" (declared at line 122 of "C:CCStudio_v3.3MyProjects130823 copy copy seam track1111 6 11thincludeDSP28_PieCtrl.h")
error: expected a ";"

该错误提示发生在：PieCtrl.PIEIER1.bit.INTx7=1;

请问这个编译错误该如何解决，谢谢！ 此帖出自小平头技术问答
