1 Glossary
This section gives a brief definition of acronyms and terms used in this document:
● Block
A block is a set of bytes that can be programmed or erased in one single programming
operation. Operations that are available on a block are fast programming, erase only,
and standard programming (which includes an erase operation). Refer to Section 2:
Memory organization for details on block size according to the device.
● Bootloader
The bootloader is an IAP application embedded in the system memory of the device. It
is used to erase and program the device using a standard serial communication port.
The bootloader is not available on small devices, and is not described in the present
document. Refer to STM8 bootloader user manual (UM0500) for more details.
● Driver
A driver is a control program defined by the application developer. It is used to manage
the allocation of system resources to start application programs. In this document two
drivers are described, ICP and IAP drivers.
● In-application programming (IAP)
IAP is the ability to re-program the Flash program memory and data EEPROM (DATA)
of a microcontroller while the device is already plugged-in to the application and the
application is running.
● In-circuit programming (ICP)
ICP is the ability to program the Flash program memory and data EEPROM of a
microcontroller using the SWIM protocol while the device is plugged-in to the
application.
● In-circuit debugging (ICD)
ICD is the ability to debug the user software using the SWIM protocol. The user has the
ability to connect the device to a debugger and insert breakpoints in his firmware.
Debugging may be intrusive (application patched to allow debugging) or non intrusive
(using a debug module).
● Memory access security system (MASS) keys
The Memory access security system (MASS) consists of a memory write protection
lock designed to prevent unwanted memory modifications due to EMS or program
counter loss. To unlock the memory protection, one or more keys must be written in a
dedicated register and in a specific order. When the operation (write or erase) is
completed, the MASS must be activated again to provide good memory security.
