Assumes no conflicts between CPU and DMA.
Programmed via the XTIMING registers or extendable via
external XREADY signal.
1-wait is minimum wait states allowed on external waveforms
for both reads and writes on XINTF.
0-wait minimum for writes assumes write buffer enabled and
not full.
Assumes no conflicts between CPU and DMA. When DMA
and CPU attempt simultaneous conflict, 1-cycle delay is
added for arbitration.
Programmed via the Flash registers.
1-wait is minimum number of wait states allowed. 1-wait-state
operation is possible at a reduced CPU frequency.
Programmed via the Flash registers.
0-wait minimum for paged access is not allowed
1-wait-state operation is possible at a reduced CPU
frequency.
Wait states of password locations are fixed.

The DMA has a base of 4 cycles/word.
The F2833x (C28x+FPU) family is a member of the TMS320C2000 digital signal controller (DSC)
platform. The C28x+FPU based controllers have the same 32-bit fixed-point architecture as TI's existing
C28x DSCs, but also include a single-precision (32-bit) IEEE 754 floating-point-unit (FPU). It is a very
efficient C/C++ engine, hence enabling users to develop not only their system control software in a
high-level language, but also enables math algorithms to be developed using C/C++. The device is as
efficient in DSP math tasks as it is in system control tasks that typically are handled by microcontroller
devices. This efficiency removes the need for a second processor in many systems. The 32 x 32-bit MAC
capabilities of the F2833x and its 64-bit processing capabilities, enable it to efficiently handle higher
numerical resolution problems. Add to this the fast interrupt response with automatic context save of
