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 OTP/
EPROM.
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 OTP/EPROM.
1.3.3.2 Data RAM/EEPROM
In ST62T53C, T60C, T63C and ST62E60C devic-
es, 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 regis-
ters, the peripheral data and control registers, the
interrupt option register and the Data ROM Win-
dow 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.
