mbed_official 441:d2c15dda23c1 6 ;* Description : STM32F070x8/STM32F070xB devices vector table for MDK-ARM toolchain.
mbed_official 441:d2c15dda23c1 7 ;* This module performs:
mbed_official 441:d2c15dda23c1 8 ;* - Set the initial SP
mbed_official 441:d2c15dda23c1 9 ;* - Set the initial PC == Reset_Handler
mbed_official 441:d2c15dda23c1 10 ;* - Set the vector table entries with the exceptions ISR address
mbed_official 441:d2c15dda23c1 11 ;* - Branches to __main in the C library (which eventually
mbed_official 441:d2c15dda23c1 12 ;* calls main()).
mbed_official 441:d2c15dda23c1 13 ;* After Reset the CortexM0 processor is in Thread mode,
mbed_official 441:d2c15dda23c1 14 ;* priority is Privileged, and the Stack is set to Main.
