Section 25
25.3.10 Interrupt Select Register 4 (ISR4)
ISR4 selects the interrupt requests to the INTC to be indicated in interrupt flag register 4. When a
bit in ISR4 is cleared to 0, the corresponding interrupt is requested as a USBFI0 interrupt. When a
bit is set to 1, the corresponding interrupt is requested as a USBFI1 interrupt. With the initial
value, each of the interrupt source flags in the interrupt flag register 4 is selected as a USBFI0
interrupt.
25.3.11 Interrupt Enable Register 0 (IER0)
IER0 enables the interrupt requests of the interrupt flag register 0. When an interrupt flag is set to
1 while the corresponding bit of each interrupt is set to 1, the interrupt request set in the interrupt
select register 0 is issued.
When an interrupt flag is set to 1 while the corresponding bit of each interrupt is set to 1, the
INTN pin set in the interrupt select register 0 is asserted low and an interrupt request is issued.
