5.2.4
Read-out protection (ROP)
The STM8A provides a read-out protection of the code and data memory which can be
activated by an option byte setting (see the ROP option byte in section 10).
The read-out protection prevents reading and writing program memory, data memory and
option bytes via the debug module and SWIM interface. This protection is active in all device
operation modes. Any attempt to remove the protection by overwriting the ROP option byte
triggers a global erase of the program and data memory.
The ROP circuit may provide a temporary access for debugging or failure analysis. The
temporary read access is protected by a user defined, 8-byte keyword stored in the option
byte area. This keyword must be entered via the SWIM interface to temporarily unlock the
device.
If desired, the temporary unlock mechanism can be permanently disabled by the user.
5.3
Single wire interface module (SWIM) and debug module
5.3.1
SWIM
The single wire interface module, SWIM, together with an integrated debug module, permits
non-intrusive, real-time in-circuit debugging and fast memory programming. The interface
can be activated in all device operation modes and can be connected to a running device
(hot plugging).The maximum data transmission speed is 145 bytes/ms.
