Hardware Description
4.5 I2C Interface
The AM273x SoC supports three I2C interfaces: MSS_I2CA, RCSS_I2CA, and RCSS_I2CB. The MSS_I2CA
lines are muxed out of the controller by default, while the RCSS_I2CA and RCSS_I2CB lines require pin muxing
to be accessible. Information regarding the locations of the I2C modules for the AM273x can be found in the Pin
Attributes section of the AM273x data sheet.
