ST7 addressing modes
The ST7 Core features 17 different addressing modes which can be classified in seven main
groups:
Table 37.
The ST7 instruction set is designed to minimize the number of bytes required per
instruction: To do so, most of the addressing modes may be subdivided in two submodes
called long and short:
●
●
The ST7 Assembler optimizes the use of long and short addressing modes.

Mode
Long addressing mode is more powerful because it can use the full 64 Kbyte address
space, however it uses more bytes and more CPU cycles.
Short addressing mode is less powerful because it can generally only access page
zero (0000h - 00FFh range), but the instruction size is more compact, and faster. All
memory to memory instructions use short addressing modes only (CLR, CPL, NEG,
BSET, BRES, BTJT, BTJF, INC, DEC, RLC, RRC, SLL, SRL, SRA, SWAP)
