description (continued)

The TMS370Cx32 family provides the system designer with an economical, efficient solution to real-time control

applications. The PACT compact development tool (CDT

™) solves the challenge of efficiently developing the

software and hardware required to design the TMS370Cx32 into an ever-increasing number of complex

applications. The application source code can be written in assembly and C language, and the output code can

be generated by the linker. Precise real-time, in-circuit emulation and extensive symbolic debug and analysis

tools ensure efficient software and hardware implementation as well as a reduced time-to-market cycle.

The TMS370Cx32 family together with the TMS370 PACT CDT370, BP programmer, starter kit, software tools,

the SE370C732A reprogrammable devices, comprehensive product documentation, and customer support

provide a complete solution to the needs of the system designer.

central processing unit (CPU)

The CPU on the TMS370Cx32 device is the high-performance 8-bit TMS370 CPU module. The ’x32 implements

an efficient register-to-register architecture that eliminates the conventional accumulator bottleneck. The

complete ’x32 instruction map is shown in Table 15.

The ’370Cx32 CPU architecture provides the following components:

CPU registers:

D A stack pointer (SP) that points to the last entry in the memory stack

D A status register (ST) that monitors the operation of the instructions and contains the global interrupt-enable

bits

D A program counter (PC) that points to the memory location of the next instruction to be executed

A memory map that includes:

D 256-byte general-purpose RAM that can be used for data memory storage, program instructions, general

purpose register, dual-port RAM, or the stack

D The upper 128-bytes of the register file is called dual-port RAM that contains the capture registers, the

circular buffer, and a command/definition area.

D A peripheral file that provides access to all internal peripheral modules, system-wide control functions, and

EEPROM/ EPROM programming control

D 256-byte EEPROM module that provides in-circuit programmability and data retention in power-off

conditions

D 8K-byte ROM or 8K-byte EPROM
