Addressing Capabilities
2.2.16 Absolute Short Addressing Mode
In this addressing mode, the operand is in memory, and the address of the operand is in the
extension word. The 16-bit address is sign-extended to 32 bits before it is used. .
2.2.17 Absolute Long Addressing Mode
In this addressing mode, the operand is in memory, and the operand’s address occupies the
two extension words following the instruction word in memory. The first extension word
contains the high-order part of the address; the second contains the low-order part of the
address. .
