采用MALAB IDE V8.53， PIC24FJ64GA010，烧录没有问题并且运行正常，但是就不能进入Debug模式，在Debug模式烧录Debug代码后，出现以下提示
Programming Target...

ICDWarn0046:  Because clock switching is enabled, MPLAB ICD 2 requires the user to cycle target power after a program operation.

ICD0161: Verify failed (MemType = Config, Address = 0xABFC, Expected Val = 0xFA1E, Val Read = 0x0)
ICD0275:  Programming failed.
MPLAB ICD 2 ready for next operation


始终没找到原因，很奇怪我在PIC24FJ64GA006的一块板子上都没问题，下面是我的配置字
_CONFIG2(FNOSC_PRI & FCKSM_CSECME & OSCIOFNC_ON & FCKSM_CSECME & POSCMOD_HS )
_CONFIG1(JTAGEN_OFF & FWDTEN_OFF & WINDIS_OFF & ICS_PGx1)


请各位大侠帮忙看看，折腾了好久都没能解决
