# RG B
*1 0 0 Branch on byte (A) not equal to imm8
*1 0 0 Branch on word (A) not equal to imm16
*2 1 0 Branch on byte (ear) not equal to imm8
*3 0 (b) Branch on byte (eam) not equal to imm8
*4 1 0 Branch on word (ear) not equal to imm16
*3 0 (c) Branch on word (eam) not equal to imm16
*5 2 0 Branch on byte (ear) = (ear) - 1, (ear) not equal to 0
*6 2 2 x (b) Branch on byte (eam) = (eam) - 1, (eam) not equal to 0
*5 2 0 Branch on word (ear) = (ear) - 1, (ear) not equal to 0
*6 2 2 x (c) Branch on word (eam) = (eam) - 1, (eam) not equal to 0
20 0 8 x (c) Software interrupt
16 0 6 x (c) Software interrupt
17 0 6 x (c) Software interrupt
20 0 8 x (c) Software interrupt
*8 0 *7 Return from interrupt
6 0 (c) Saves the old frame pointer in the stack upon entering the
function, then sets the new frame pointer and reserves the
local pointer area.
5 0 (c) Recovers the old frame pointer from the stack upon exiting the
function.
4 0 (c) Return from subroutine
6 0 (d) Return from subroutine
