Function Documentation

void RESET_SetPeripheralReset

(

reset_ip_name_t

peripheral

)

Asserts reset signal to specified peripheral module.

Parameters

peripheral

Assert reset to this peripheral. The enum argument contains encoding of reset register and reset bit position in the reset register.

void RESET_ClearPeripheralReset

(

reset_ip_name_t

peripheral

)

Clears reset signal to specified peripheral module, allows it to operate.

Parameters

peripheral

Clear reset to this peripheral. The enum argument contains encoding of reset register and reset bit position in the reset register.

void RESET_PeripheralReset

(

reset_ip_name_t

peripheral

)

Reset peripheral module.

Parameters

peripheral

Peripheral to reset. The enum argument contains encoding of reset register and reset bit position in the reset register.

static uint32_t RESET_GetResetSource ( void  )

inlinestatic

Returns

Reset source, use return source to AND _reset_source to get the related status.
