LDR (Load Register)

Loads a value into a Destination register.

32-bit Load Operations (LDR)

These instructions load 32-bit values into a register, completely overwriting its previous contents.

Load Immediate

0x10 LDR rDst, imm32

Loads a constant 32-bit value directly into the destination register.

Argument	Description
rDst	The destination register where the data will be stored.
imm32	The 32-bit value to load into the destination register.

Load Index

0x11 LDR rDst, [rIdx]

Uses the address stored in rIdx to load a 32-bit value from memory into rDst.

Argument	Description
rDst	The destination register where the data will be stored.
rIdx	The register containing the memory address to read from.

Load Offset

0x12 LDR rDst, [rIdx + imm16]

Adds a signed 16-bit offset to rIdx to form an effective address, then loads the 32-bit value at that address into rDst.

Argument	Description
rDst	The destination register where the data will be stored.
rIdx	The base register containing the memory address.
imm16	A signed offset (−32,768 to 32,767) added to the base address.

Load Scaled Offset

0x13 LDR rDst, [rIdx + rOff * imm4]

Computes an effective address as rIdx + (rOff × imm4), then loads the 32-bit value at that address into rDst. This is particularly useful for indexing into arrays with a known element stride.

Argument	Description
rDst	The destination register where the data will be stored.
rIdx	The base register containing the memory address.
rOff	The register whose value is scaled and added to the base address.
imm4	A 4-bit scale factor (0–15) multiplied with rOff to form the offset.

Load Absolute

0x14 LDR rDst, [imm32]

Loads the 32-bit value from the fixed memory address specified by imm32.

Argument	Description
rDst	The destination register where the data will be stored.
imm32	The 32-bit absolute address to read from.
