5;* Description        : HK32F030x devices vector table for MDK-ARM toolchain.
6;*                      This module performs:
7;*                      - Set the initial SP
8;*                      - Set the initial PC == Reset_Handler
9;*                      - Set the vector table entries with the exceptions ISR address
10;*                      - Branches to __main in the C library (which eventually
11;*                        calls main()).
12;*                      After Reset the CortexM0 processor is in Thread mode,
13;*                      priority is Privileged, and the Stack is set to Main.
