 		 #178899 - need help getting started with AT89S52
hi guys i am a beginner and just getting started with electronics.
I haven't done much practically only read theoretically.

now i want to start experimenting on AT89S52
so i built a regulated power supply using 7805.
i need to program the micro controller serially so i read in datasheet that
P1.5 to incoming data
P1.6 to outgoing data
and P1.7 to sclk = 11.0592 Mhz/ 16

<***>my first question is how do i give that frequency to P1.7

                                             it's a linear error?            01/01/70 00:00      
                                                Don't introduce "linear" in the equation            01/01/70 00:00

                                                      Still no linearity claimed. Just "more out of spec bader"            01/01/70 00:00      
                                                         Not obvious            01/01/70 00:00      
                                                            I agree            01/01/70 00:00
