memory map

The TMS370Cx4x family architecture is based on the Von Neumann architecture, where the program memory

and data memory share a common address space. All peripheral input/output is memory mapped in this same

common address space. As shown in Figure 3, the TMS370Cx4x family provides memory-mapped RAM, ROM,

data EEPROM, EPROM, input/output pins, peripheral functions, and system interrupt vectors.

The peripheral file contains all input/output port control, peripheral status and control, EPROM and EEPROM

memory programming, and system-wide control functions. The peripheral file is located between 1010h and

107Fh and is logically divided into seven peripheral file frames of 16 bytes each. Each on-chip peripheral is

assigned to a separate frame through which peripheral control and data information is passed.
