If I don't want to use the IDACs what is the recommended connection for the IDAC pins?
* If any or all the IDACs are not used then connect the pins as follows:
* IREF: If no IDACs are used then connect a low cost 3k3 ohm resistor to ground.
* If no PVDD supply available then connect PVDDx of all IDACs to AVDD_REG1 (Ball F10).
o Make sure not to power up such IDACs because that would load AVDD_REG1 unnecessarily.
* CDAMPx of any IDAC not used leave unconnected.
* IDACx of individual IDAC not used:
o Power down IDACx using PD bit (IDACxCON = 1; it is already powered down after reset)
o Set IDACxDAT = 0 (zero current; it is already 0 after reset),
o Connect IDACx pin to PGND.
