I2C Slave mode can generate a glitch at SCL
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.
Verify that SCL is low before writing USICNT register.
