Enabling ROP in application?

Posted on November 08, 2017 at 07:47

Hello. Is it possible to enable ROP in application? Let's say I transmit a command to MCU through UART and then MCU enables ROP. I am using STM8AF6223.

It is stated in PM0051 that 'readout protection is enabled by writing 0xAA in the ROP option byte'. But in

STM8AF6213/23/23A/26

 datasheet [8.1 Option byte description], OPT0 (ROP[7:0]) -> 

'0xAA: Enable readout protection (write access via SWIM protocol)

Note: Refer to STM8S series and STM8AF series 8-bit microcontrollers reference manual (RM0016) section on Flash/EEPROM memory readout protection for details.'

Maybe it is possible to enable it without using SWIM protocol?

Thank you
