Though the default configuration provides flash acceleration, advanced users may desire
to customize the FMC buffer configurations to maximize throughput for their use cases.
For example, the user may adjust the controls to enable buffering per access type (data or
instruction).
NOTE
When reconfiguring the FMC, do not program the control and
configuration inputs to the FMC while the program flash
memory is being accessed. Instead, change them with a routine
executing from RAM in supervisor mode.
