用語(terms)
| Term | Description |
|---|---|
| Data block | A data block may contain 1..n bytes and is used within the API of the EEPROM, driver.Data blocks are passed with - Address offset in EEPROM - Pointer to memory location- Length , to the EEPROM driver. |
| Data unit | The smallest data entity in EEPROM. The entities may differ for read/write/erase operation., Example 1: Motorola STAR12, Read: 1 byte, Write: 2 bytes, Erase: 4 bytes, Example 2: external SPI EEPROM device, Read/Write/Erase: 1 byte |
| Normal mode, Burst mode | Some external SPI EEPROM devices provide the possibility of different access modes: - Normal mode: The data exchange with the EEPROM device via SPI is performed byte wise. This allows for cooperative SPI usage together with other SPI devices like I/O ASICs, external watchdogs etc. - Burst mode: The data exchange with the EEPROM device via SPI is performed block wise. The block size depends on the EEPROM properties, an example is 64 bytes. Because large blocks are transferred, the SPI is blocked by the EEPROM access in burst mode. This mode is used during ECU start-up and shut-down phases where fast reading/writing of data is required. |
| EEPROM cell | Smallest physical unit of an EEPROM device that holds the data. Usually 1 byte. |
| EEPROM | Electrically Erasable and Programmable Read Only Memory |
| NVRAM | Non Volatile Random Access Memory |
| NvM | Module name of NVRAM Manager |
| EcuM | Module name of ECU State Manager |
| DEM | Module name of Diagnostic Event Manager |
| DET | Module name of Default Error Trace |
