ST631xx Data Space (Continued) MEMORY SPACES (Continued) Data Space The instruction set of the ST631xx Core operates on a specific space, named Data Space that con- tains all the data necessary for the processing of the program. The Data Space allows the address- ing of RAM (256 bytes for the ST631xx family), EEPROM (128 bytes), ST631xx Core/peripheral registers, and read-only data such as constants and the look-up tables. ® ST63140,142,126,156 12/82 |
