Hide
There was a pending interrupt that immediately fired once the I2C hardware interrupt was created again in I2CCC32XX_open(). To support a general restart use-case, the following was added to I2CCC32XX_open(), before the calls to HwiP_create() and initHw():

1) Reset the I2C peripheral

2) Clear any pending interrupt request in the NVIC by calling HwiP_clearInterrupt(hwAttrs->intNum)
