Introduction
Purpose
This document details the design in the FDD and also lists out any deviations which were made from the design for the implementation due to any constraints in development. ExcpnHndlg MDD describes the exception handling / reset cause determination for microcontroller diagnostics

Software Component Implementation
Sub-Module Functions
Init: ExcpnHndlgInit1
Design Rationale
Non-RTE function because it needs to be called before the OS is started - so that floating point exceptions can be enabled before anything uses floating point
Module Outputs
None
Init: ExcpnHndlgInit2
Design Rationale
RTE function to initialize all the NTCs to pass
Module Outputs
None
Per: ExcpnHndlgPer1
Design Rationale
RTE Periodic function called every 2 ms to check for OS errors
Store Module Inputs to Local copies
Refer MDD
(Processing of function)………
Triggered on Timing Event every 2ms
Store Local copy of outputs into Module Outputs
None

UNIT TEST CONSIDERATION
The PIMs listed in the Data dictionary file BackUpRam and ExcpnHndlgOsErrCod are non RTE PIMS which need special memory mapping and are not generated through RTE. Hence use the component level variable name as used in the component for these PIMs
