The diode across V

and V
PP
may be omitted (shorted), if the application does not require use of the scan port interface.
The same applies for the 1-kΩ resistor which appears at the RESET pin; the resistor may be shorted if not using the scan
port. However, the footprint for the resistor is strongly recommended for any MSP50C614 production board. Refer to the
Important Note regarding Scan Port Bond Out appearing in Chapter 7.

(MSP50P614 only)
Note, that there are five V
DD
pins and five V
SS
pins. Each of these should be
connected, with the separate decoupling capacitors (0.1 µF) included for each
V
