# Abstract Platformとの関係
センサ類の入出力の共通化を測る。 
Classic Platformのドライバ類に共通な仕様で、Adaptive Platformでも必要な機能を抜き出す。

ISO 各種規格に基づいた診断、通信の抽象的な定義をする。
必要があれば国際規格を改定する。

<この項は書きかけです。順次追記します。>


## 文書変更(Document Change) 
>• Obsolete requirements related to Mode Switch are removed
• Immediate block with CRC condition was transitioned to recommendation
## 用語(terms)

|Term|Description|
|:--|:--|
| Basic Storage Object | A "Basic Storage Object" is the smallest entity of a "NVRAM block". Several "Basic Storage Objects" can be used to build a NVRAM Block. A "Basic Storage Object" can reside in different memory locations (RAM/ROM/NV memory).
| NVRAM Block | The "NVRAM Block" is the entire structure, which is needed to administrate and to store a block of NV data.
| NV data | The data to be stored in Non-Volatile memory.
| Block Management Type | Type of the NVRAM Block. It depends on the (configurable) individual composition of a NVRAM Block in chunks of different mandatory/optional Basic Storage Objects and the subsequent handling of this NVRAM block.
| RAM Block | The "RAM Block" is a "Basic Storage Object". It represents the part of a "NVRAM Block" which resides in the RAM. See [SWS_NvM_00126]
| ROM Block | The "ROM Block" is a "Basic Storage Object". It represents the part of a "NVRAM Block" which resides in the ROM. The "ROM Block" is an optional part of a "NVRAM Block". [SWS_NvM_00020]
| NV Block| The "NV Block" is a "Basic Storage Object". It represents the part of a "NVRAM Block" which resides in the NV memory. The "NV Block" is a mandatory part of a "NVRAM Block".[SWS_NvM_00125]
| NV Block Header| Additional information included in the NV Block if the mechanism "Static Block ID" is enabled.
|Administrative Block | The "Administrative Block" is a "Basic Storage Object". It resides in RAM. The "Administrative Block" is a mandatory part of a "NVRAM Block". [SWS_NvM_00135]
| DET | Default Error Tracer - module to which development errors are reported.
| DEM | Diagnostic Event Manager - module to which production relevant errors are reported
| NV | Non volatile
| FEE | Flash EEPROM Emulation
| EA | EEPROM Abstraction
| FCFS | First come first serve
