Notes: 1. PUSH Rn is equivalent to MOV.W Rn, @–SP.
POP Rn is equivalent to MOV.W @SP+, Rn. The same applies to the machine
language.
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.
