IOCF [0~7] TCC / EP0 / USB Suspend / USB Reset / Port 7 State Change /SPI /USB
Only when the global interrupt is enabled by the ENI instruction will the individual
interrupt work. After the DISI instruction, any interrupt will not work even if the
respective control bits of IOCF are set to 1.
The USB Host Resume Interrupt works only in Dual clock mode. This is because when
the MCU is in sleep mode, it will be automatically woken up by the UDC Resume signal.

Host Resume interrupt enable bits. These eight bits control the TCC
interrupt function, EP0 interrupt, USB Suspend interrupt, USB Reset
interrupt, Port 7 State Change interrupt, SPI interrupt and USB Host
Resume interrupt respectively. Individual interrupt is enabled by setting
its associated control bit in the IOCF to "1."
