Hello @daniel_meier,
The User and Integration manuals are mainly describing the AUTOSAR high-level driver functions (which in consequence, use the lower-level functions). If you require further information about the IP lower-level APIs, you can refer to the LPit_Gpt_Ip.h header.
For example, for Lpit_Gpt_Ip_Init:
/**
* @brief Function Name : Lpit_Gpt_Ip_Init
* @details Driver initialization function for LPit instance.
*
*
* @param[in] instance LPIT hw instance number
* @param[in] config Pointer to a selected configuration structure
* @return void
* @pre The data structure including the configuration set required for initializing the driver
*
*/
void Lpit_Gpt_Ip_Init(uint8 instance, const Lpit_Gpt_Ip_InstanceConfigType *config);
Best regards,
Julián
