HMS9xC7132 / HMS9xC7134

22. INSTRUCTION SET

The HMS9xC7132 uses a powerful instruction set which permits

the expansion of on-chip CPU peripherals and optimizes byte ef-

ficiency and execution speed. Assigned opcodes add new high-

power operation and permit new addressing modes.

The instruction set consists of 49 single-byte, 46 two-byte and 16

three-byte instructions. When using a 12MHz oscillator, 64 in-

•Arithmatic operations

structions execute in 1us and 45 instructions execute in 2us. Mul-

tiply and divide instructions execute in 4 us.

For the description of the Date Addressing modes and Hexadeci-

mal opcode cross-reference see Boolean variable manipula-

tion,Program brranching.
