MEMORY MAP (Cont’d)

1.3.3 Data Space

Data Space accommodates all the data necessary

for processing the user program. This space com-

prises the RAM resource, the processor core and

peripheral registers, as well as read-only data

such as constants and look-up tables in Program

memory.

1.3.3.1 Data ROM

All read-only data is physically stored in program

memory, which also accommodates the Program

Space. The program memory consequently con-

tains the program code to be executed, as well as

the constants and look-up tables required by the

application.

The Data Space locations in which the different

constants and look-up tables are addressed by the

processor core may be thought of as a 64-byte

window through which it is possible to access the

read-only data stored in Program memory.

1.3.3.2 Data RAM/EEPROM

In ST6230B and ST62E30B devices, the data

space includes 60 bytes of RAM, the accumulator

(A), the indirect registers (X), (Y), the short direct

registers (V), (W), the I/O port registers, the pe-

ripheral data and control registers, the interrupt

option register and the Data ROM Window register

(DRW register).

Additional RAM and EEPROM pages can also be

addressed using banks of 64 bytes located be-

tween addresses 00h and 3Fh.

1.3.4 Stack Space

Stack space consists of six 12-bit registers which

are used to stack subroutine and interrupt return

addresses, as well as the current program counter

contents.
