Set the USB resume signal interrupt status flag to “0” after the
wake-up sequence process. The USB resume detect flag goes to
“0” at the same time. When the clock operation is started up with
a remote wake-up, set the USB remote wake-up bit to “1” after the
wake-up sequence process. (keep it set to “1” for a minimum of 10
ms and maximum of 15 ms). By doing this, the MCU will send a
resume signal to the host CPU and let it know that the suspend
state has been released.
After that, set the USB remote wake-up bit and the USB suspend
detection flag to “0”, because the USB suspend detection flag is
not automatically cleared to “0” with a remote wake-up.
[USB Control Register] USBC
When using the USB function, the USB enable bit must be set to
“1”. The USB line driver supply bit must be set to “0” (DC-DC con-
verter is disabled) when operating at Vcc = 3.3V. In this condition,
the setting of the USB line driver current control bit has no effect
on USB operations.

USB control register (address 001316)
USBC
Reserved bit (“0” at read/write)
USB default state selection bit (USBC1)
0: In default state after power-on/reset
1: In default state after USB reset signal received
Reserved bit (“0” at read/write)
USB line driver current control bit (USBC3)
0: High current mode
1: Low current mode
USB line driver supply enable bit (USBC4) (Note 1)
0: Line driver disabled
1: Line driver enabled
USB clock enable bit (USBC5)
0: 48 MHz clock to the USB block disabled
1: 48 MHz clock to the USB block enabled
Reserved bit (“0” at read/write)
USB enable bit (USBC7)
0: USB block disabled (Note 2)
1: USB block enabled
Notes 1: When using the MCU in Vcc = 3.3 V, set this bit to “0” and disable the built-in DC-DC converter
2: Setting this bit to 0” causes the contents of all USB registers to have the values at reset.
