STM32L031x6 custom bootloader

Hello!  I manage to write a custom boot loader in STM32L031E6 using I2C interface.  To do so, it requires the MCU to provide at least the following features:


1. Reallocation of vector table

2. API functions for internal flash read/write/erase


For (1), I know the there is a vector register VTOR available in STM32L031E6 to reallocate vector table.  However, I cannot find any information of (2).  Could anyone advise how can I do and anything I have missed out?  Many Thanks!
