&par Example Description

This example provides a description of how to program the OB address.
After Reset, the Flash will be unlocked. Then erase the OB and
write data in user data. In the end, lock the flash.The data of the address
after erasing and programing will be displayed on serial assistant through USART1.

using USART1(TX:PA9, RX:PA10).
  - USART1 configured as follow:
  - BaudRate    =  115200
  - Word Length =  USART_WordLength_8b
  - Stop Bit    =  USART_StopBits_1
  - Parity      =  USART_Parity_No
  - Hardware flow control disabled (RTS and CTS signals)
  - Receive and transmit enabled
