I'm building a basic USB board of MSP430F5515 and I need to verify a few component values before manufacturing as they have different values in different application notes:
1- Do I need the AVCC components if I'm not using the ADC at all?
2- If the application is battery powered (unless plugged to host), is there a software method to detect USB plug so that the MCU wakes up from LPM3 or should I do it using HW as shown in (2), (i.e. detect a rising edge of VUSB at a MCU pin)?
3- The PUR and USB resistor values have different values on the launchpad of 5529 and this document (SNOU157A - TMP1075EVM), Are both ok?
4- The Launchpad crystal is discontinued, is the following used part ok? Also the 33KHz Crystal is optional, correct?
5/6- The decoupling Capacitor values are also different between the launchpad and the aforementioned application note, both fine?
Finally, with the below circuit, can I flash the Firmware using the USB port? Is there anything missing on this schematic for the sake of programming? I noticed the launchpad doesn't connect the JTAG pins of the Target MCU unlike simplelink family.
