SRAM Data Memory
Figure 3-8 shows how the ATA6289 SRAM Memory is organized. The ATA6289 is a complex
microcontroller with more peripheral units than can be supported within the 64 locations
reserved in the Opcode for the IN and OUT instructions. For the Extended I/O space from 0x60 -
0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used. The lower 768
data memory locations address both the Register File, the I/O memory, Extended I/O memory,
and the internal data SRAM. The first 32 locations address the Register File, the next 64 location
the standard I/O memory, then 160 locations of Extended I/O memory, and the next 512 loca-
tions address the internal data SRAM. The five different addressing modes for the data memory
cover: Direct, Indirect with Displacement, Indirect, Indirect with Pre-decrement, and Indirect with
Post-increment. In the Register File, registers R26 to R31 feature the indirect addressing pointer
registers. The direct addressing reaches the entire data space. The Indirect with Displacement
mode reaches 63 address locations from the base address given by the Y- or Z-register. When
using register indirect addressing modes with automatic pre-decrement and post- increment, the
address registers X, Y, and Z are decremented or incremented.
The 32 general purpose working registers, 64 I/O Registers, 160 Extended I/O Registers, and
the 512bytes of internal data SRAM in the ATA6289 are all accessible through all these
addressing modes. The Register File is described in Section 3.5.4 “General Purpose Register
Figure 3-8.
