Detection and classification enable for each port.
When in Manual mode, setting a bit means that only one cycle (detection or classification) is performed for the corresponding port. The bit is automatically cleared when the cycle has been completed.
NOTE
The same result can be obtained by writing to the Detect/Class Restart Register.
NOTE
Write commands to either 0x12, 0x18, 0x19, or 0x1A require an I2C bus processing delay of 1.2 ms when followed by a Detect/Class Enable (0x14) write command. This delay applies from the end of the 0x12, 0x18, 0x19, or 0x1A command (stop pulse) to the end of the Detect/Class Enable command (stop pulse).
It is also cleared if a port turn off (Power Enable Register) is issued.
In Semi-Auto Mode, while the port is not powered up, detection and classification are performed continuously, as long as the CLEn and DETEn bits are kept set. First, detection is performed. If a Resistance valid status is returned, classification follows. After, the detect-class sequence repeats. If a valid status is not returned by the detection event, classification is skipped, and detection is repeated.
In Auto Mode, if the port is not powered up and the DETEn and CLEn bits are set, classification follows a valid detect, and power-on follows classification unless classification returns Unknown, Overcurrent or Class Mismatch Status.
During the cool-down cycle following a Start, ICUT or ILIM, any Detect/Class Enable command for that port are delayed until the end of the cool-down period.
NOTE
At the end of the cool-down period, one or more detection/class cycles are automatically restarted as described previously if the detect enable bit is set.
