Notes: 1. PUSH Rn is equivalent to MOV.W Rn, @–SP.
POP Rn is equivalent to MOV.W @SP+, Rn. The machine language is also the same.
2. Bcc is the generic term for conditional branch instructions.
The functions of the instructions are shown in tables 2.4 to 2.11. The meaning of the operation
symbols used in the tables is as follows.
