(1) I = input, O = output
(2) N/A = not available
(3) Short unused analog input pairs and connect them to analog ground (see Section 7.4 for recommendations on all unused pins).
(4) Not available on MSP430i2021 and MSP430i2020 devices.
(5) Not available on MSP430i2031 and MSP430i2030 devices.
(6) 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 Section 8.7.7.2).
(7) VCORE is for internal use only. No external current loading is possible. Connect VCORE to only the recommended capacitor value (CVCORE) (see Section 8.3).
