MSP430G2553: Device is working without Vcc

Part Number: MSP430G2553

Hello TI experts,

My customer now tests MSP430G2553 for their new product, and they found one problem.

- they will use ADC function, so they applied 3.3V to pin4 for test.

- this MCU is working even they did not apply DVCC and AVCC.

- they tested with TI basic examples ; Software toggle and Basic Clock. it was same.

is it normal operation? or definitely a problem?

please check this issue. Thanks.

Best regards,
