 		 #98702 - not, if you are very sneeky
Responding to: ???'s previous message
You can't use movx,because movx send a data to an address

not, if you are very sneeky
If you do movx @dptr,a with DPH holding your high byte and a holding your low byte and have a 16 bit register connected to P2P0 which is clocked by !WR, you will, in effect, have a synchronous write of 16 bits. This, of course, excludes any possibility of external memory of any kind unless you REALLY go wild with the hardware. You can, however, not read 16 bits by this mechanism.
