The diode across V
DD
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 C614 production board. Refer to the
Important
Note regarding Scan Port Bond Out
appearing in Chapter 7.

(MSP50P614 only)
Note that there are 5 each of the pins V
DD
and V
SS
. Each of these should be
connected, with separate decoupling capacitors (0.1 µF) included for each
V
DD
.
