10 INSTRUCTION SET
10.1 CPU ADDRESSING MODES
The CPU features 17 different addressing modes
which can be classified in seven main groups:
The CPU Instruction set is designed to minimize
the number of bytes required per instruction: To do
so, most of the addressing modes may be subdi-
vided in two submodes called long and short:
– Long addressing mode is more powerful be-
cause it can use the full 64 Kbyte address space,
however it uses more bytes and more CPU cy-
cles.
– 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 in-
structions use short addressing modes only
(CLR, CPL, NEG, BSET, BRES, BTJT, BTJF,
INC, DEC, RLC, RRC, SLL, SRL, SRA, SWAP)
The ST7 Assembler optimizes the use of long and
short addressing modes.
