6.18 USI4

USI Module

Category

Functional

Function

I2C Slave mode can generate a glitch at SCL

Description

USI I2C Slave Operation at slower communication rates (less than 20kbps). During I2C bus active operation, if USICNT is written while SCL is high, I2C module will generate a glitch on SCL that can corrupt the I2C bus sequence.

Workaround

Verify that SCL is low before writing USICNT register.

For HP8/G2MICRO/MSP430V334 device, the erratum is listed as I2C1.

I2C16: MSP430V334 I2C Slave Mode

Function: MSP430V334 I2C Slave Device can generate a glitch on SCL

Description: MSP430V334 I2C slave operation can generate glitches when operated at slow communication rates (less than 20 kbps) and this can corrupt the I2C bus sequence.

Workaround: None
