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。

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
