9 / 86 page 9/86 ST62T55C ST62T65C/E65C 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 ST62T55C, ST62T65C and ST62E65C 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.
