`ao_sys_pfm_ws_set`

#define ao_sys_pfm_ws_set(ws)                                           \
{                                                                       \

    PRECONCLR = _PRECON_PFMWS_MASK & ~((ws) << _PRECON_PFMWS_POSITION); \
}

Sets the program flash memory (PFM) access time defined in terms of SYSCLK wait states.

#define ao_sys_pref_disable()        \
{                                    \
    PRECONCLR = _PRECON_PREFEN_MASK; \
}

Disables predictive prefetch.

#define ao_sys_pref_enable_any()     \
{                                    \
    PRECONSET = _PRECON_PREFEN_MASK; \
}

Enables predictive prefetch for any address.
