#114217 - I suggest you do not Responding to: ???'s previous message |
I suggest you read the "MCS-51 user manual" for more detailed info on the hardware:
http://www.intel.com/design/mc...272383.htm I suggest you do not. This link takes a very long time to download and include much stuff that has no value today, the significant parts can be fetched much faster through these 3 links Chapter 1 http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf chapter 2 http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf chapter 3 http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf "There are no requirements on the duty cycle of the external clock signal, because the input to the internal clock circuitry is through a divide-by-two flip-flop." Typical techwriter gobbelygook. yes, the clock is fed to a flip flop, yes, ANY clocked flip-flop will "divide by 2". Have a look at fig.15 on page 12 of ch1 and come back with "there is a divide by 2 of the clock" Erik |
