AT32UC3A
• FRZCLK: Freeze USB Clock
Set to disable the clock inputs (the resume detection is still active). This reduces power consumption. Unless explicitly
stated, all registers then become read-only.
Clear to enable the clock inputs.
Note that this bit can be set/cleared even if USBE = 0 or FRZCLK = 1. Disabling the USB controller (by clearing the USBE
bit) does not reset this bit, but this freezes the clock inputs whatever its value.
• USBE: USB Macro Enable
Set to enable the USB controller.
Clear to disable and reset the USB controller, to disable the USB transceiver and to disable the USB controller clock inputs.
Unless explicitly stated, all registers then become read-only and are reset.
Note that this bit can be set/cleared even if USBE = 0 or FRZCLK = 1.
• TIMVALUE: Timer Value
Set to initialize the new value of the special timer register selected by TIMPAGE.
• TIMPAGE: Timer Page
Write the page value to access a special timer register.
• UNLOCK: Timer Access Unlock
Set to unlock the TIMPAGE and TIMVALUE fields before writing them.
Reset to lock the TIMPAGE and TIMVALUE fields.
Note that the TIMPAGE and TIMVALUE fields can always be read, whatever the value of UNLOCK.
• UIDE: USB_ID Pin Enable
Set to select the USB mode (device/host) from the USB_ID input pin.
Clear to select the USB mode (device/host) with the UIMOD bit.
Note that this bit can be set/cleared even if USBE = 0 or FRZCLK = 1. Disabling the USB controller (by clearing the USBE
bit) does not reset this bit.
• UIMOD: USB Macro Mode
This bit has no effect when UIDE = 1 (USB_ID input pin activated).
Set to select the USB device mode.
Clear to select the USB host mode.
Note that this bit can be set/cleared even if USBE = 0 or FRZCLK = 1. Disabling the USB controller (by clearing the USBE
bit) does not reset this bit.
