I2C Address Register

t-sugiyama — Sun, 05 Apr 2020 15:13:09 GMT

Hello,
I have a question about {16.1.4.1 Initialization sequence} in i.MX 8M Mini Applications Processor Reference Manual, Rev. 2, 08/2019.
I am wondering about the following:
"2.Update the address in the (I2C_IADR) to define its slave address (address can range from 0 to 0x7f)."
What should I set in the I2C_IADR register when I consider to make the i.MX8Mmini an I2C master?
Is the transfer destination slave ID correct?
I think that I2C_IADR should be set only when making i.MX8Mmini an I2C slave device.
Thanks.

Tetsuya.

Hi Tetsuya

>I think that I2C_IADR should be set only when making i.MX8Mmini an I2C slave device.

I think you are right.

One can look at i2c master example in uboot:

mxc_i2c.c\i2c\drivers - uboot-imx - i.MX U-Boot

Best regards
