High Level Assembler - Opcodes overview, Extension Sets EC40-EC4F

The table below lists all documented extended mnemonics for instructions:

Opcode Mnemonic Description Table Type
EC42 LOCHI Load On Condition from Halfword Immediate Extended Mnemonics
EC46 LOCGHI Load On Condition Grande from Halfword Immediate Extended Mnemonics
EC4E LOCHHI Load On Condition fullword High from Halfword Immediate Extended Mnemonics

Each extended mnemonic links to a text section with some additional info on the pertinent pseudo opcode.

Opcode Assignments.

Remark:
Please note that the creation of descriptions for all individual instructions is an ongoing process. As yet no such descriptions have been created for the opcodes on this page.

Extended Mnemonics for instructions in extension sets EC40-EC4F

All instructions in this table are six bytes in length. The first byte always has a value of X'EC', the second byte of the opcode is located in the sixth byte of the instruction and has a value in the range from X'40' through X'4F'. The second half of the second byte is the mask to be used for determining whether or not to execute the instruction. This mask designates the exact pseudo opcode.

The second nibble in the table indicates the mask value for the condition code for the pertinent instructions. In the assembled instructions this is the second half of the second byte.

    Tyrannosaurus Rex Dinos are not dead. They are alive and well and living in data centers all around you. They speak in tongues and work strange magics with computers. Beware the dino! And just in case you're waiting for the final demise of these dino's: remember that dinos ruled the world for 155-million years!
