Hi,
They are not functions but defined addresses which are used in other files, e.g. PH_HAL_GPIO_CONFIGOUTPUT_ADDR (0x00007fd9) is used in file phhalGpio.h below:
...
#include "PN7462AU_ROM3.h"
#include "ph_Status.h"
...
#define phhalPcr_ConfigOutput(dwGpioNumber, dwEnableAsOuput, dwSlewRate) \
((phhalPcr_ConfigOutput_t *) \
PH_HAL_GPIO_CONFIGOUTPUT_ADDR)\
(dwGpioNumber, dwEnableAsOuput, dwSlewRate)
Hope this helps.
BR,
Ivan.
