ETAMPDET - External Tamper Detect

Description

External Tamper Detect (ETAMPDET) Peripheral API.

Function Documentation

◆ sl_etampdet_init()

void sl_etampdet_init ( const sl_etampdet_config_t *  config)

Initialize ETAMPDET.

Parameters
[in]configThe pointer to the initialization structure.
Note
User should call sl_etampdet_init_channel() for full initialization. This function should be called before sl_etampdet_init_channel()
The control registers setting of the GPIOs to be used by ETAMPDET should be at the default values to ensure that other clients are not accidentally driving the GPIOs that ETAMPDET is using.
