*** − The DM640 device does not support the VP1 peripheral; therefore, the
I/O/Z IPD McBSP1 peripheral pins are standalone peripheral functions, not muxed.

† _{I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground}
‡ _{IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the opposite}
supply rail, a 1-kΩ resistor should be used.)
§ _{These pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.}
