<> 144:ef7eb2e8f9f7 8 * This module performs:

<> 144:ef7eb2e8f9f7 10 * - Set the initial PC == Reset_Handler,
<> 144:ef7eb2e8f9f7 11 * - Set the vector table entries with the exceptions ISR address
<> 144:ef7eb2e8f9f7 12 * - Branches to main in the C library (which eventually

<> 144:ef7eb2e8f9f7 14 * After Reset the Cortex-M0 processor is in Thread mode,
