Always up-to-date information can be found here. It may be not be up to date with official ARM UAL guidelines at the time you are using it. The information provided on this page is given on an as is basis, for the purpose of supporting the VisUAL application and its users to debug code. For EQU, expression can be any numerical expression. Azure Resource Manager templates are JavaScript Object Notation (JSON) files that define the infrastructure and configuration for your project.This can be used to return from a subroutine.

Branch with link BL is identical to branch, with the additional function that the link register is set to point to the next line of code before the branch is performed.

This instruction will cause the program to "jump", i.e.

The target for a branch instruction B must be a label on a line.

The operation of these instructions is provided in detail on this ARM Infocenter page. You can also use aliases for these as described in the link that follows.

This can be one of full ascending FA, full descending FD, empty ascending EA, and empty descending ED.

For LDM and STM instructions, indicates stack direction.

You can observe memory access operations and compare word/byte modes using the "Show Memory" visualisation feature. Note that the convention for byte addressing is Little Endian. If B is used, the byte at the given address is loaded instead.

By default, the LDR / STR instructions load a word (32 bits) from the memory at the given address.

For detailed information and examples, press Ctrl+Space when typing an instruction opcode in the code editor.

A short summary of the instruction syntax is given below. These are primarily arithmetic, logical, load/store and branch instructions. VisUAL supports a small subset of ARM UAL instructions.
