MSP430F6638的RESET脚电平为0V时,芯片不复位,求教?

Other Parts Discussed in Thread: MSP430F6638

我的MSP430F6638板子上自带板载仿真器,仿真器部分电路和TI官网的5529开发板一样

MSP430F6638工作电压3.3V

通过板载仿真器供电时,6638的TEST脚为2.8V,  RESET脚为3.3V

按下复位键时,RESET脚被拉低为0V,但是此时6638正常工作,没有被复位,

请问这是什么问题呢?

顺便,如果仍通过,板载仿真器供电,6638工作电压3.3V

但是此时如果将TEST的跳线拔除,

6638的TEST脚上的电压为0V,

此时按下RESET键,6638能被正常复位。
