6.6 I2C_ERR_03

I2C peripheral mode cannot wake up device when sourced from MFCLK

Revisions Affected

Rev X

Description

IF I2C module is configured in peripheral mode
AND I2C is clocked from MFCLK (Middle Frequency Clock)
AND device is placed in STOP2 or STANDBY0/1 power modes,
THEN I2C fails to wakeup the device when receiving data.

Workaround

Set I2C to be clocked by BUSCLK instead of MFCLK, if needing low power wakeup upon receiving data in I2C peripheral mode.
