when the program exits from isr last scanning status retained ,to avoid that JNB instructions are used. remove that lines and run your program to check the effect. I have stopped the main program using 'sjmp $'. you can remove that and enter your program loop there. then you have to use some...

Check th voltage on Vref/2 pin ,you should make it 1.28V to get exact temperature. Or you can apply correction on software side according to your reference.
set some levels in between 0 an 1024. then compare the read value with these levels and assign values to variable b. for example if you want 10 different speeds as in your program one level should be of size 93 (1024/11) and they are 0-93, 93-186, 186-279 etc. Now get the current ADC reading...
