Instruction Set

13-3

Assembly Language Instructions

The ’C3x supports 35 2-operand arithmetic and logical instructions. The two
operands are the source and destination. The source operand can be a memory
word, a register, or a part of the instruction word. The destination operand is
always a register.

As shown in Table 13–2, these instructions provide integer, floating-point or
logical operations, and multiprecision arithmetic.
