DATA[15:0]:
The indirect access data (DATA[15:0]) bits hold the data transfer to or from an indirect register
during indirect access. When RWB is set to logic 1 (indirect read), the data from the
addressed location in the register will be transferred to DATA[15:0]. BUSY should be polled
to determine when the new data is available in DATA[15:0]. When RWB is set to logic 0
(indirect write), the data from DATA[15:0] will be transferred to the register. The indirect Data
register must contain valid data before the indirect write is initiated by writing to the Indirect
Address Register.
