 		 #159916 - SETB from 20h to 2FH
Responding to: ???'s previous message
The SETB command in the classic 8051 architecture supports addresses 20H to 2FH (128 bits). It also supports SFR registers whose address ends in xxxxx000B. (Another 128 bits).

Address 34H is not supported. The ACC.x and Px.x addresses end in xxxxx000.

That is why it is good to keep your flags in 20-2F
