FUNCTION

0bank

Bits 5–3 of global transfer source/destination register code (bit 6 assumed to be 0)

Adstbnk

Bits 6–3 of ALU destination register code

As1bank

Bits 6–3 of ALU source 1 register code

bank

Bits 6–3 of global (or local) store source or load destination

Conditional choice of D register for src1 operand of the ALU

Protect status register’s carry bit

cond

Condition code

D register or lower 3 bits of register code for local transfer source/destination

Duplicate least significant data during moves

dst

The three lowest bits of the register code for move or field move destination

dstbank

Bits 6–3 of move destination register code

Sign extend local (bit 31), sign extend global (bit 9)

Conditional global transfer

Global address register for load, store, or address unit arithmetic

Gim / X

Global address unit immediate offset or index register

Gmode

Global unit addressing mode

Grm

Global PP-relative addressing mode

itm

Number of item selected for field extract move

L = 1 selects load operation, L = 0 selects store / address unit arithmetic operation

Local address register for load, store, or address unit arithmetic

Lim / X

Local address unit immediate offset or index register

Lmode

Local unit addressing mode

Lrm

Local PP-relative addressing mode

Protect status register’s negative bit

Conditional write of ALU result

reg

Enable index scaling. Additional index bit for byte accesses or arithmetic operations (bit 28, local; bit 6, global)

size

Size of data transfer (bits 30 – 29, local; bits 8 – 7, global)

src

Three lowest bits of register code for register-register move source or non-field moves. D register source for field move
