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 a conditional branch instruction in which cc represents a condition code.

The following sections give a concise summary of the instructions in each category, and indicate

the bit patterns of their object code. The notation used is defined next.

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.
