LF: new commands
There is a concise list of assembly language mnemonics in the last
link of 68000 pointers on Tim Gerla's page.
In that listing they give "Bcc" as conditional branch
A couple pages down they say:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Condition Codes set after CMP D0,D1 Instruction.
Relationship Unsigned Signed
------------ -------- ------
D1 < D0 CS - Carry Bit Set LT - Less Than
D1 <= D0 LS - Lower or Same LE - Less than or Equal
D1 = D0 EQ - Equal (Z-bit Set) EQ - Equal (Z-bit Set)
D1 != D0 NE - Not Equal (Z-bit Clear) NE - Not Equal (Z-bit Clear)
D1 > D0 HI - HIgher than GT - Greater Than
D1 >= D0 CC - Carry Bit Clear GE - Greater than or Equal
PL - PLus (N-bit Clear) MI - Minus (N-bit Set)
VC - V-bit Clear (No Overflow) VS - V-bit Set (Overflow)
RA - BRanch Always
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So, you have BCS,BLS,BEQ,BNE,BHI,BCC,BPL,BVC,BRA,BLT,BLE,BEQ,BNE,BGT,BGE,
BMI,BVS
I told my girlfriend that my calculator has "bra" and "dbra" instructions,
but she said I was still a geek...
