#137706 - Strange Questions on 8051 |
Dear all,
I have a list of questions which left me clueless check out. 1. How is the machine cycle of a processor(for 8051 its 12 clock cycles) calculated? See its same for all 8051 family members though they are designed by different logics- CMOS,LS,HSMOS.... 2. Instruction cycle in 8051 is a combination of how many and what cycles(read cycle,write cycle,fetch cycle.....)? 3. Data sheets say that 8051 has an internal oscillator then why do we need a crystal oscillator for 8051(connected to 18,19 pins)? |
