Notes: 1. PUSH Rn is equivalent to MOV.W Rn, @−SP.
POP Rn is equivalent to MOV.W @SP+, Rn.
2. B
CC
is a conditional branch instruction in which cc represents a condition code.
3. Not supported by the H8/338 Series.
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.
