MSP430FR2633: NA

Part Number: MSP430FR2633
Other Parts Discussed in Thread: MSP-FET,

I need to use all GPIO pins from MSP430FR2633. That means I need to share jtag with gpio pins. According to the datasheet, Test pin should set high to enable jtag and pulled down to GND for GPIO. I am using MSP-FET to program the device and my question is does MSP-FET automatically enable 3.3V to Test Pin which is pin 8. I checked the MSP-FET datasheet but wasn't able to find the definite answer. Thanks in advance.

    Hello,

    The TEST and RST pins are not muxed with GPIO functionality. As such, you can utilize them for 2-wire JTAG (SBW), and still have full debug and programming functionality.  If you have your debug circuit wired up in SBW mode, the MSP-FET will detect that and utilize SBW mode for debug and programming. 

    In application, you can set the traditional JTAG capable pins to GPIO functionality.
