You can lookup a single instruction by typing LD in the instruction field, which will show all load instructions. You can also lookup multiple instructions like LD,CMP.
You can also lookup mnemonics like LDX,LDY in the mnemonic field.

STBT r,sBit,dBit,addr
Store value of a Register Bit into Memory (DPM).dstBit' <- r.srcBit
The STBT instruction stores the value of a speciï¬ed bit in either the A, B or CC registers to a speciï¬ed bit in memory. None of the Condition Code ï¬ags are affected by the operation. The usefulness of the STBT instruction is limited by the fact that only Direct Addressing is permitted.
