Question, i.MX6DQ I2C Repeated Start

[Aemj]

Hi All,

My customer is trying to implement I2C Repeated Start handling into his software.

He needs to know when RSTA bit should be set or clear.

Could you show me when RSTA bit should be set or clear for Repeated Start?

BR,

Miyamoto

Hello Miyamoto,

RSTA bit is used in I2C master mode to generate the repeated start signal. Set the RSTA bit to 1 to generate the repeated start signal and then poll the IBB bit for '1'. Complete example can be found at drivers/i2c/busses/i2c-imx.c.

Peter
