  <a href="https://ww1.microchip.com/downloads/en/DeviceDoc/SAM_D5x_E5x_Family_Data_Sheet_DS60001507G.pdf" rel="nofollow noreferrer">SAME51N19</a> facing Issues while transferring the data on <strong>address 0b0101001=0x29</strong>. Also, checking on oscilloscope not getting good. Attaching the oscilloscope image. I'm using I2C on standard mode. As master generates the clock and slave use the same, I think we don't need to set clock as slave or in slave controller. <strong>DefaultSharedI2CClockFrequency = 400000;</strong> Please help me to solve the issue.
  Checked the connections SDA-SDA &amp; SCL-SCL
