Notes:

1. A Thumb BLX contains two consecutive Thumb instructions, and takes four cycles.

The Thumb instruction set is a re-encoded subset of the ARM instruction set. 

The Thumb instruction set is divided into:

• Branch instructions

• Data processing instructions

• Load and Store instructions

• Load and Store multiple instructions

• Exception-generating instruction

Table 5 shows the Thumb instruction set, for further details, see the ARM Technical Reference Manual.

 gives the Thumb instruction mnemonic list.
