7.32 I2C_ERR_04

I2C Module

Category

Functional

Function

When SCL is low and SDA is high the Target i2c is not able to release the stretch.

Description

1: SCL line grounded and released, device indefinitely pulls SCL low.

2: Post clock stretch, timeout, and release; if there is another clock low on the line, device indefinitely pulls SCL low.

Workaround

If the I2C target application does not require data reception in low power mode using Async fast clock request, disabling SWUEN by default is recommended, including during reset or power cycle. In this case, bug description 1 and 2 does not occur.

If the I2C target application requires data reception in low power mode using Async fast clock request, enable SWUEN just before entering low power and clear SWUEN after low power exit. Even in this scenario, bug description 1 and 2 can occur when the I2C target is in low power, it will indefinitely stretch the SCL line if there is a continuous clock stretching or timeout caused by another device on the bus. To recover from this situation, enable the low timeout interrupt on the I2C target device, reset and re-initialize the I2C module within the low timeout ISR.
