ST7 FAMILY
PROGRAMMING MANUAL
The ST7 family of HCMOS Microcontrollers has been designed and built around an industry standard 8-
bit core and a library of peripheral blocks, which include ROM, EPROM, RAM, EEPROM, I/O, Serial In-
terfaces (SPI, SCI, I2C,...), 16-bit Timers, etc. These blocks may be assembled in various combinations
in order to provide cost-effective solutions for application dedicated products.
The ST7 family forms part of the SGS-THOMSON Microelectronics 8-bit MCU product line, and finds
place in a wide variety of applications such as automotive systems, remote controls, video monitors, car
radio and numerous other consumer, industrial, telecom, multimedia and automotive products.
ST7 ARCHITECTURE
The 8-bit ST7 Core isdesigned for high code efficiency. It contains 6 internal registers, 17 main address-
ing modes and 63 instructions. The 6 internal registers include 2 Index registers, an Accumulator, a 16-
bit Program Counter,a Stack Pointer and a Condition Code register. The two Indexregisters X andY en-
able Indexed Addressing modes with or without offset, along with read-modify-write type data manipula-
tions. These registers simplify branching routines and data modifications.
The 16-bit Program Counter is able to address up to 64K of ROM/EPROM memory. The 6-bit Stack
Pointer provides access to a 64-level Stack and an upgradeto an 8-bit Stack Pointer is foreseen in order
to be able to manage a 256-level Stack. The Core also includes a Condition Code Register providing 5
Condition Flags that indicate the result of the last instruction executed.
The17 main Addressing modes, including Indirect Relative and Indexed addressing, allow sophisticated
branchingroutines or CASE-type functions. TheIndexed Indirect Addressing mode, for instance, permits
look-up tables to be located anywhere in the address space, thus enablingvery flexible programming and
compact C-based code.
The 63-instruction Instruction Set is 8-bit oriented with a 2-byte average instruction size. This Instruction
Set offers, in addition to standard data movement and logic/arithmetic functions, byte multiplication, bit
manipulation,data transfer betweenStack and Accumulator(Push/Pop) with direct stack access, aswell
as data transfer using the X and Y registers.
Depending of the target device, different methods of Interrupt priority management may be selected: the
number of Interrupt vectors can vary from 6 to 16, and the priority level may be managed by software on
some versions. Some peripherals include Direct Memory Access (DMA) between serial interfaces and
memory.
Power-saving may be managed under program control by placing the device in WAIT or HALT mode.
A high test coverage is achieved for ST7 family devices thanks to the use of an autotest method based
on ”Cyclic Redundancy Checking” (CRC). This approach is based on the analysis ofa data flow compris-
ing not only input and output, but also internal data, whichaffords a detailed inside viewof the behaviour
of the core and of the peripherals.
