22.3.5 Interrupt Select Register 1 (ISR1)
ISR1 selects the vector numbers of the interrupt requests indicated in interrupt flag register 1
(IFR1). If the USB issues an interrupt request to the INTC when a bit in ISR0 is cleared to 0, the
interrupt corresponding to the bit will be USBINTN2. If the USB issues an interrupt request to the
INTC when a bit in ISR0 is set to 1, the corresponding interrupt will be USBINTN3.
Bit Bit Name

Value
R/W Description
7 to 3 All 0 R Reserved
These bits are always read as 0. The initial value
should not be changed.
2 EP3 TR 1 R/W EP3 Transfer Request
1 EP3 TS 1 R/W EP3 Transmission Complete
0 VBUSF 1 R/W USB Bus Connect
22.3.6 Interrupt Select Register 2 (ISR2)
ISR2 selects the vector numbers of the interrupt requests indicated in interrupt flag register 2
(IFR2). If the USB issues an interrupt request to the INTC when a bit in ISR0 is cleared to 0, the
interrupt corresponding to the bit will be USBINTN2. If the USB issues an interrupt request to the
INTC when a bit in ISR0 is set to 1, the corresponding interrupt will be USBINTN3.
