Hello !


I'm going to use full JTAG interface on K82 e.g A0-A3 and A5 pins.

Should those pins be really configured as JTAG pins by using ConfigTools or possible to leave those pins as non configured for have low power consumption when MCU in low power mode ?

Or I really should configure those as JTAG pins after start up and configure them as float according recommendation ?


I understand this configuration bring Analog input configuration :


PORT_SetPinMux(PORTx, NU, kPORT_PinDisabledOrAnalog); 


But what mean float ? Do not call API for set pin muxing at all ?


I would like to configure all relevant gpio pins by using recommendation from DataSheet :


5.2 Recommended connection for unused analog and digital
