the Indirect Memory Data registers. The address within a memory table can
be found in the Indirect Memory Address register.
MEM_BUSY:
The indirect memory access status bit (MEM_BUSY) reports the progress of
an indirect access. A write to the Indirect Memory Command register triggers
an indirect access and sets MEM_BUSY to a logic 1; MEM_BUSY will remain
logic 1 until the access is complete. This register should be polled to
determine when data from an indirect read operation is available in the TIMA
Indirect Memory Data registers or to determine when a new indirect write
operation may commence.
