ATAM893-D
4.2
Components of MARC4 Core
The core contains ROM, RAM, ALU, program counter, RAM address registers, instruction
decoder and interrupt controller. The following sections describe each functional block in more
detail.
4.2.1
Program Memory
The program memory (EEPROM) is programmable with the customer application program. The
EEPROM is addressed by a 12-bit wide program counter, thus predefining a maximum program
bank size of 4 Kbytes. The lowest user program memory address segment is taken up by a 512-
byte zero page which contains predefined start addresses for interrupt service routines and spe-
cial subroutines accessible with single byte instructions (SCALL).
The corresponding memory map is shown in Figure 4-2. Look-up tables of constants can 0also
be held in ROM and are accessed via the MARC4’s built-in table instruction.
Figure 4-2.

4.2.2
RAM
The ATAM893-D contains 256
× 4-bit wide static random access memory (RAM). It is used for
the expression stack, the return stack and data memory for variables and arrays. The RAM is
addressed by any of the four 8-bit wide RAM address registers SP, RP, X and Y.
4.2.2.1
Expression Stack
The 4-bit wide expression stack is addressed with the expression Stack Pointer (SP). All arith-
metic, I/O and memory reference operations take their operands from, and return their results to
the expression stack. The MARC4 performs the operations with the top of stack items (TOS and
TOS-1). The TOS register contains the top element of the expression stack and works in the
same way as an accumulator. This stack is also used for passing parameters between subrou-
tines and as a scratch pad area for temporary storage of data.
