mbed_official 5:ac9f6c2c45e8 6 ;* Description : STM32F042x4/STM32F042x6 devices vector table for MDK-ARM toolchain.
mbed_official 5:ac9f6c2c45e8 7 ;* This module performs:
mbed_official 5:ac9f6c2c45e8 8 ;* - Set the initial SP
mbed_official 5:ac9f6c2c45e8 9 ;* - Set the initial PC == Reset_Handler
mbed_official 5:ac9f6c2c45e8 10 ;* - Set the vector table entries with the exceptions ISR address
mbed_official 5:ac9f6c2c45e8 11 ;* - Branches to __main in the C library (which eventually
mbed_official 5:ac9f6c2c45e8 12 ;* calls main()).
mbed_official 5:ac9f6c2c45e8 13 ;* After Reset the CortexM0 processor is in Thread mode,
mbed_official 5:ac9f6c2c45e8 14 ;* priority is Privileged, and the Stack is set to Main.
