What does it do?		01/01/70 00:00
I activate MOVC Disable.		01/01/70 00:00

Things you can and can't do ...		01/01/70 00:00
it does		01/01/70 00:00

case		01/01/70 00:00
Errr...		01/01/70 00:00
There is more than just switch/case		01/01/70 00:00
No C without MOVC		01/01/70 00:00
Protection on other derivatives		01/01/70 00:00
Example - AT89C51		01/01/70 00:00
AT89C51 can do MOVC internal !		01/01/70 00:00
nope		01/01/70 00:00
LPC Protection		01/01/70 00:00
naah, but make it quite a bit more difficult		01/01/70 00:00
Compiler Optimisation		01/01/70 00:00
sure, but there will still be MOVC		01/01/70 00:00
And upgrading the compiler can change the output		01/01/70 00:00
the ICEman cometh		01/01/70 00:00
I have found no issues with the ICE		01/01/70 00:00
sure it 'works'		01/01/70 00:00

Confused		01/01/70 00:00
jmp @dptr is not movc		01/01/70 00:00
jmp @dptr is a computed goto not a jump table		01/01/70 00:00
what requires a movc???		01/01/70 00:00
Jump TABLE		01/01/70 00:00
