mbed_official 378:be043393235b 8 * This module performs:
mbed_official 378:be043393235b 9 * - Set the initial SP
mbed_official 378:be043393235b 10 * - Set the initial PC == Reset_Handler,
mbed_official 378:be043393235b 11 * - Set the vector table entries with the exceptions ISR address
mbed_official 378:be043393235b 12 * - Branches to main in the C library (which eventually
mbed_official 378:be043393235b 13 * calls main()).
mbed_official 378:be043393235b 14 * After Reset the Cortex-M0+ processor is in Thread mode,
mbed_official 378:be043393235b 15 * priority is Privileged, and the Stack is set to Main.
