EXECUTION TIME FROM SRAM AND FLASH/EE
This section describes SRAM and Flash/EE access times during
execution of applications where execution time is critical.
Execution from SRAM
Fetching instructions from SRAM takes one clock cycle because
the access time of the SRAM is 2 ns and a clock cycle is 22 ns
minimum. However, if the instruction involves reading or
writing data to memory, one extra cycle must be added if the
data is in SRAM (or three cycles if the data is in Flash/EE), one
cycle to execute the instruction and two cycles to obtain the
32-bit data from Flash/EE. A control flow instruction, such as a
branch instruction, takes one cycle to fetch, but it also takes
two cycles to fill the pipeline with the new instructions.
Execution from Flash/EE
Because the Flash/EE width is 16 bits and access time for 16-bit
words is 23 ns, execution from Flash/EE cannot be completed in
one cycle (contrary to a SRAM fetch, which can be completed in
a single cycle when CD bits = 0). Dependent on the instruction,
some dead times may be required before accessing data for any
value of CD bits.
In ARM mode, where instructions are 32 bits, two cycles are
needed to fetch any instruction when CD = 0. In Thumb mode,
where instructions are 16 bits, one cycle is needed to fetch any
instruction.
Timing is identical in both modes when executing instructions
that involve using Flash/EE for data memory. If the instruction
to be executed is a control flow instruction, an extra cycle is
needed to decode the new address of the program counter and
then four cycles are needed to fill the pipeline. A data processing
instruction involving only core registers does not require any
extra clock cycles, but if it involves data in Flash/EE, an extra
clock cycle is needed to decode the address of the data and two
cycles to obtain the 32-bit data from Flash/EE. An extra cycle
must also be added before fetching another instruction. Data
transfer instructions are more complex and are summarized in

With 1 < N ≤ 16, N is the number of bytes of data to load or
store in the multiple load/store instruction. The SWAP instruction
combines an LD and STR instruction with only one fetch,
giving a total of eight cycles plus 40 μs.
