0xAA: Disable readout protection (write access via SWIM protocol)
Refer to Readout protection section in the STM8L15x and STM8L16x reference manual (RM0031).
0x00: UBC is not protected.
0x01: Page 0 is write protected.
0x02: Page 0 and 1 reserved for the UBC and write protected. It covers only the interrupt vectors.
0x03: Page 0 to 2 reserved for UBC and write protected.
0x7F to 0xFF - All 128 pages reserved for UBC and write protected.
The protection of the memory area not protected by the UBC is enabled through the MASS keys.
Refer to User boot code section in the STM8L15x and STM8L16x reference manual (RM0031).
