I
This bit is set to 1 to enable clock stretching. When SCL is low, setting this bit forces the device to hold SCL low
until I2CMSEN is cleared. If SCL is high, setting this bit forces the device to hold SCL low after the next falling edge.
This bit is cleared to disable clock stretching.
I
This bit is set to enable loopback test mode. In this mode, the SCL and SDA signals are connected internally to
their respective input signals.
This bit is cleared by the user to disable loopback mode.
I
This bit is set to allow the device to compete for control of the bus even if another device is currently driving a
start condition.
This bit is cleared to back off until the I
