`ao_sys_pfm_ws_set`

#define ao_sys_pfm_ws_set(ws)                                               \
{                                                                           \

        CHECONCLR = _CHECON_PFMWS_MASK & ~((ws) << _CHECON_PFMWS_POSITION); \
}

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

`ao_sys_pref_disable`

#define ao_sys_pref_disable()        \
{                                    \
    CHECONCLR = _CHECON_PREFEN_MASK; \
}

Disables predictive prefetch.

`ao_sys_pref_enable_both`

#define ao_sys_pref_enable_both()    \
{                                    \
    CHECONSET = _CHECON_PREFEN_MASK; \
}

Enables predictive prefetch for both cacheable and non-cacheable regions.

`ao_sys_pref_enable_cacheable`

#define ao_sys_pref_enable_cacheable()                                \
{                                                                     \

    CHECONSET = _CHECON_PREFEN_MASK & (1 << _CHECON_PREFEN_POSITION); \
}

Enables predictive prefetch for cacheable regions.

`ao_sys_pref_enable_non_cacheable`

#define ao_sys_pref_enable_non_cacheable()                            \
{                                                                     \
    CHECONCLR = _CHECON_PREFEN_MASK;                                  \
    CHECONSET = _CHECON_PREFEN_MASK & (2 << _CHECON_PREFEN_POSITION); \
}

Enables predictive prefetch for non-cacheable regions.
