Symbols in Operation Column

•

extu()....... indicates a zero extension operation, in which values lacking higher bits are complemented

by adding the value "0" as necessary.

•

extn()....... indicates a minus extension operation, in which values lacking higher bits are complemented

by adding the value "1" as necessary.

•

exts() ....... indicates a sign extension operation in which a zero extension is performed for the data

within ( ) in which the MSB is 0 and a minus extension is performed for the data in which the
MSB is 1. 

•

( )............. indicates  indirect  addressing, which values reading or loading from/to the memory address

where the registers within ( ) or the formula indicate.

•

{ }............ indicates the calculation priority; ( ) is used for specifying indirect address
