6.9 I2C_ERR_07

I2C Module

Category

Functional

Function

Back to back controller control register writes can cause I2C to not start.

Description

Back to back CTR register writes can cause the next CTR.START to not properly cause the start condition.

Workaround

Write all the CTR bits including CTR.START in a single write or wait between the CTR writes and CTR.START write.
