Description
Subtracts "Oper" from "Dest" and stores the result back into "Dest". The result of the subtraction is capped at 0. If the Source Bank is 0 then the “Oper” is subtracted from the destination value. If the Source Bank is an 8 bit bank, then the “Oper” is the address in that bank where the operand is.
