 		 #172882 - pull up on ds1307 sqwout
Responding to: Michael Karas's previous message
i was able to solve the problem by using pullup resister on pin 7 sqwout of DS1307 . i also had to clear CH bit on seconds 00h resister. Now iam getting
1 Hz output frequency . With this iam now sure that my i2c write routine is correct. Now i will proceed further with RTC.
