3.16.2.8 Overall Operation Sequence
The overall operation sequence of UDC2AB is as follows:
1. Hardware reset
2. Set the interrupt signal
3. Detect the USB bus power supply (connect) and initialize
4. USB enumeration response
5a. Master Read transfer
5b. Master Write transfer
6. USB bus power supply disconnection
Note: While UDC2AB originally has the function to assert the int_powerdetect interrupt when

In the Interrupt Enable register, set the required bit of the interrupt source to
“Enable.” See section 3.16.2.7 “Interrupt Signal (INTS[21])” for more
information.
See section 3.16.2.11 “USB Bus Power Detecting Sequence” for more
information.
See section 3.16.3.4 “USB Device Response” in the section of UDC2.
Make a Master Read transfer corresponding to the receiving request from the
USB host. See section 3.16.2.9 “(1) Master Read transfer” for more
information.
Make a Master Write transfer corresponding to the sending request from the
USB host. See section 3.16.2.9 “(4) Master Write transfer” for more
information.
It may be possible that USB bus power supply is disconnected at any timing.
See section 3.16.2.11 “USB Bus Power Detecting Sequence” for more
information.
