When the SD24 operates with the internal reference (SD24REFS = 1), the VREF pin must not be loaded externally. Connect only the recommended capacitor value (CVREF) from the VREF pin to AVSS (see Table 5-19).
VCORE is for internal use only. No external current loading is possible. Connect VCORE to only the recommended capacitor value (CVCORE) (see Section 5.3).
Short unused analog input pairs and connect them to analog ground (see Section 4.4 for recommendations on all unused pins).
These pins are not available on the 28-pin PW package. Program these four pins to output direction and drive value 0 in software.
Not available on MSP430i2031 and MSP430i2030 devices.
Not available on MSP430i2021 and MSP430i2020 devices.
