我在使用MSP430F5xx_6xx的driverlib时  在调用#include "timer_a.c"时会报错，错误如下：

Error[Pe020]: identifier "OFS_TAxCTL" is undefined F:driverlibMSP430F5xx_6xx imer_a.c 79
Error[Pe020]: identifier "OFS_TAxCTL" is undefined F:driverlibMSP430F5xx_6xx imer_a.c 183
。。。。。。。。

此类错误有十几个，把#include "timer_a.c“屏蔽  就ok了，请问大家是什么问题？ 源程序如下
