hi, thanks for ur response.
but this still doesnt solve the problem, that even after disabling all interrupts, why am i still getting ints? is there some behaviour of gpio ints that im not aware of? like, the order in which to execute the instructions: clearing the ifg, enabling io int etc.. thanks, karan On Thu, 2004-10-14 at 01:45, Albert Bartoszko wrote: > Hi Karan > > [...] > > i have been trying to simulate the I2C STOP condn. > > for the slave. > > so upon pressing button2 on the master, > > the clk and the data lines go high. > > this is the webpage im using as i2c reference: > > http://perso.club-internet.fr/mbouget/i2c-faq.html > > specifically: > > http://perso.club-internet.fr/mbouget/i2c-faq.html#IC_017 > > This says: > "The SDA and SCL lines can only be PULLED low.
