References SUPC_MR_KEY_PASSWD.

void supc_disable_monitor_interrupt

(

Supc *

Parameters

p_supc

Pointer 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_supc

Pointer to a SUPC instance.

void supc_enable_brownout_detector

(

Supc *

p_supc

)

Enable the core brownout detector.

Parameters

p_supc

Pointer 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_supc

Pointer 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_supc

Pointer 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_supc

Pointer to a SUPC instance.

uint32_t supc_get_status

(

Supc *

p_supc

)

Get supply controller status.

Parameters

p_supc

Pointer 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_supc	Pointer to a SUPC instance.
ul_period	Supply monitor sampling period.

void supc_set_monitor_threshold	(	Supc *	p_supc,
		uint32_t	ul_threshold
	)

Set Supply monitor threshold.

Parameters

p_supc	Pointer to a SUPC instance.
ul_threshold	Supply 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_bypass

0 for Xtal, 1 for bypass.
