I'm developing with the MKL1732ZVFM4, I'm using the I2C0 in VLPR at a 100kHz speed, the core is drive by the LIRC of 8MHz, the core is running at 4MHz and the bus & flash at 1MHz. I've Review the baud generator of the MCUXpresso API & the multiplier and divider of the F register values are updating correctly. What else could be generating the frequency error? The freq espected is of 100kHz & the freq measured by an scope is 90.4kHz
