The core contains ROM, RAM, ALU, program counter, RAM address registers, instruc-

tion decoder and interrupt controller. The following sections describe each functional

block in more detail:

ROM

The program memory (ROM) is mask programmed with the customer application pro-

gram during fabrication of the microcontroller. The ROM is addressed by a 12-bit wide

program counter, thus predefining a maximum program bank size of 2 Kbytes. An addi-

tional 1-Kbyte of ROM exists which is reserved for quality control self-test software The

lowest user ROM address segment is taken up by a 512-byte Zero page which contains

predefined start addresses for interrupt service routines and special subroutines acces-

sible with single byte instructions (SCALL).

The corresponding memory map is shown in Figure 4. Look-up tables of constants can

also be held in ROM and are accessed via the MARC4's built-in table instruction.

RAM

The ATAR080-D contains 256 x 4-bit wide static random access memory (RAM) which

is used for the expression stack. The return stack and data memory are used for vari-

ables and arrays. The RAM is addressed by any of the four 8-bit wide RAM address

registers SP, RP, X and Y.

The 4-bit wide expression stack is addressed with the expression stack pointer (SP). All

arithmetic, 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 subroutines and as a scratch pad area for temporary

storage of data.

The 12-bit wide return stack is addressed by the return stack pointer (RP). It is used for

storing return addresses of subroutines, interrupt routines and for keeping loop index

counts. The return stack can also be used as a temporary storage area.

The MARC4 instruction set supports the exchange of data between the top elements of

the expression stack and the return stack. The two stacks within the RAM have a user

definable location and maximum depth.
