Answer / rinki soni
microprocessor uses down counting hence count value is given by:
count value = required time/time period of 1 clock pulse
but in case of microcontroller as it uses up counting count value is given by:
final value- (required time/time period of 1 clock pulse)+1
+1 is added to rollover the count value to 0.

Architecture. Microprocessors use the Von Neuman
architecture while microcontrollers use the Harvard
architecture (separate instruction and data memory). I'm
not sure if this distinction still holds though.
