MEMORY SPACES (Cont’d)

1.3.3 Data Space

The ST6 Core instruction set operates on a specif-

ic space, referred to as the Data Space, which

contains all the data necessary for the program.

Figure 5. Data Space

The Data Space allows the addressing of RAM

(192 bytes), EEPROM (384 bytes plus 128 bytes

for the DDC SPI), ST6 Core and peripheral regis-

ters, as well as read-only data such as constants

and look-up tables.

*) These registers contain write only bits, in which

case the bit operation instructions are not possi-

ble.
