I2C Module
Functional
Start address match status might not be updated in time for a read through the ISR if running I2C at slow speeds.
If running at I2C speeds less than 100kHz then the ADDRMATCH bit (address match in the TSR register) might not be set in time for the read through an interrupt.
If running at below 100kHz on I2C, wait at least 1 I2C CLK cycle before reading the ADDRMATCH bit.
