NOTES

1 If the mnemonic ends in ‘‘B’’ a byte operation is performed otherwise a word operation is done Operands D B and A

must conform to the alignment rules for the required operand type D and B are locations in the Register File A can be

located anywhere in memory

4 Changes a byte to word

5 Offset is a 2’s complement number

6 Specified bit is one of the 2048 bits in the register file

7 The ‘‘L’’ (Long) suffix indicates double-word operation

8 Initiates a Reset by pulling RESET low Software should re-initialize all the necessary registers with code starting at 2080H

9 The assembler will not accept this mnemonic
