MSP430I2020: MCU can't be reset

Part Number: MSP430I2020

Hi,

I made a mistake for flash write and then MCU can't be reset.

I may erase some important value, so MCU can't be reset.

I can load new program to MCU by CCS.

But it can't work anymore.

If I run debug by CCS, it can't run and pause.

Could you help to rescue this MCU?
