According to datasheet, VDD_HV_IO_JTAG need be 3.3V if using JTAG features of those pins on MCU.
In my application, only 1.25V and 5.0V are supplied.
Can I use 5V to supply VDD_HV_IO_JTAG?
I checked with 5V applied on VDD_HV_IO_JTAG. MCU is running OK and Lauterbach debugger communication to MCU JTAG is also OK.
Is there any problem or risk of using 5V on VDD_HV_IO_JTAG?
