Universal Serial Bus Device Controller (S08USBV1)
17.3.6
The INTENB contains enabling bits for each of the interrupt sources within the USB module. Setting any of these
bits will enable the respective interrupt source in the INTSTAT register. This register will contain the value of 0x00
after a reset, i.e. all interrupts disabled.

Interrupt Enable Register (INTENB)
Error Flag — This bit is set when any of the error conditions within the ERRSTAT register has occurred. The
firmware must then read the ERRSTAT register to determine the source of the error.
0 No error conditions within the ERRSTAT register have been detected
1 Error conditions within the ERRSTAT register have been detected
USB Reset Flag —This bit is set when the USB module has decoded a valid USB reset. When asserted, this bit
will inform the MCU to automatically write 0x00 to the address register and to enable endpoint 0. USBRSTF is
set once a USB reset has been detected for 2.5 μs. It will not be asserted again until the USB reset condition has
been removed, and then reasserted.
0 No USB reset observed
1 USB reset detected
STALL Interrupt Enable — Setting this bit will enable STALL interrupts.
0 Interrupt disabled
1 Interrupt enabled
RESUME Interrupt Enable — Setting this bit will enable RESUME interrupts.
0 Interrupt disabled
1 Interrupt enabled
SLEEP Interrupt Enable — Setting this bit will enable SLEEP interrupts.
