Functions | |
uint16_t | EE_Init (void) |
Restore the pages to a known good state in case of page's status corruption after a power loss. More... | |
uint16_t | EE_ReadVariable (uint16_t VirtAddress, uint16_t *Data) |
Returns the last stored variable data, if found, which correspond to the passed virtual address. More... | |
uint16_t | EE_WriteVariable (uint16_t VirtAddress, uint16_t Data) |
Writes/upadtes variable data in EEPROM. More... | |
