void supc_disable_brownout_reset ( Supc *  p_supc)

Disable the assertion of core reset signal when a brownout detection occurs.

Parameters
p_supcPointer to a SUPC instance.

References SUPC_MR_KEY_PASSWD.

void supc_disable_monitor_interrupt ( Supc *  p_supc)

Disable the assertion of SUPC interrupt signal when a supply monitor detection occurs.

Parameters
p_supcPointer to a SUPC instance.
void supc_disable_monitor_reset ( Supc *  p_supc)

Disable the assertion of core reset signal when a supply monitor detection occurs.

Parameters
p_supcPointer to a SUPC instance.
void supc_enable_brownout_detector ( Supc *  p_supc)

Enable the core brownout detector.

Parameters
p_supcPointer to a SUPC instance.

References SUPC_MR_KEY_PASSWD.

void supc_enable_brownout_reset ( Supc *  p_supc)

Enable the assertion of core reset signal when a brownout detection occurs.

Parameters
p_supcPointer to a SUPC instance.

References SUPC_MR_KEY_PASSWD.

void supc_enable_monitor_interrupt ( Supc *  p_supc)

Enable the assertion of SUPC interrupt signal when a supply monitor detection occurs.

Parameters
p_supcPointer to a SUPC instance.
void supc_enable_monitor_reset ( Supc *  p_supc)

Enable the assertion of the core reset signal when a supply monitor detection occurs.

Parameters
p_supcPointer to a SUPC instance.
uint32_t supc_get_status ( Supc *  p_supc)

Get supply controller status.

Parameters
p_supcPointer to a SUPC instance.
Returns
The status of supply controller.
void supc_set_monitor_sampling_period ( Supc *  p_supc,
uint32_t  ul_period 
)

Set Supply monitor sampling period.

Parameters
p_supcPointer to a SUPC instance.
ul_periodSupply monitor sampling period.
void supc_set_monitor_threshold ( Supc *  p_supc,
uint32_t  ul_threshold 
)

Set Supply monitor threshold.

Parameters
p_supcPointer to a SUPC instance.
ul_thresholdSupply monitor threshold (between 1.9V and 3.4V).
void supc_switch_sclk_to_32kxtal ( Supc *  p_supc,
uint32_t  ul_bypass 
)

Switch slow clock source selection to external 32k (Xtal or Bypass) oscillator.

This function disables the PLLs.

Note
Switching sclk back to 32krc is only possible by shutting down the VDDIO power supply.
Parameters
ul_bypass0 for Xtal, 1 for bypass.
