31 / 82 page ![]() &3, Data Sheet 29 1999-07 Instruction Set Summary The table below lists the instructions of the C161PI in a condensed way. The various addressing modes that can be used with a specific instruction, the operation of the instructions, parameters for conditional execution of instructions, and the opcodes for each instruction can be found in the “C166 Family Instruction Set Manual”. This document also provides a detailled description of each instruction. Table 4 Instruction Set Summary Mnemonic Description Bytes ADD(B) Add word (byte) operands 2 / 4 ADDC(B) Add word (byte) operands with Carry 2 / 4 SUB(B) Subtract word (byte) operands 2 / 4 SUBC(B) Subtract word (byte) operands with Carry 2 / 4 MUL(U) (Un)Signed multiply direct GPR by direct GPR (16-16-bit) 2 DIV(U) (Un)Signed divide register MDL by direct GPR (16-/16-bit) 2 DIVL(U) (Un)Signed long divide reg. MD by direct GPR (32-/16-bit) 2 CPL(B) Complement direct word (byte) GPR 2 NEG(B) Negate direct word (byte) GPR 2 AND(B) Bitwise AND, (word/byte operands) 2 / 4 OR(B) Bitwise OR, (word/byte operands) 2 / 4 XOR(B) Bitwise XOR, (word/byte operands) 2 / 4 BCLR Clear direct bit 2 BSET Set direct bit 2 BMOV(N) Move (negated) direct bit to direct bit 4 BAND, BOR, BXOR AND/OR/XOR direct bit with direct bit 4 BCMP Compare direct bit to direct bit 4 BFLDH/L Bitwise modify masked high/low byte of bit-addressable direct word memory with immediate data 4 CMP(B) Compare word (byte) operands 2 / 4 CMPD1/2 Compare word data to GPR and decrement GPR by 1/2 2 / 4 CMPI1/2 Compare word data to GPR and increment GPR by 1/2 2 / 4 PRIOR Determine number of shift cycles to normalize direct word GPR and store result in direct word GPR 2 SHL / SHR Shift left/right direct word GPR 2 ROL / ROR Rotate left/right direct word GPR 2 ASHR Arithmetic (sign bit) shift right direct word GPR 2 |
