Notes: 1. EP0 interrupts must be assigned to the same interrupt request signal.
2. An EP2i DMA transfer by a USB request is specified by the EP2iT1 and EP2iT0 bits of UDMAR.
3. An EP2o DMA transfer by a USB request is specified by the EP2oT1 and EP2oT0 bits of UDMAR.
4. An EP4i DMA transfer by a USB request is specified by the EP4iT1 and EP4iT0 bits of UDMAR.
5. An EP4oDMA transfer by a USB request is specified by the EP4oT1 and EP4oT0 bits of UDMAR.
6. The suspend/resume interrupt request IRQ6 must be specified to be detected at the falling edge
(IRQ6SCB, A = 01 in ISCRH) by the interrupt controller register.
7. Available only in H8S/2215R, H8S/2215T and H8S/2215C. “—” in H8S/2215.
8. Available only in H8S/2215R, H8S/2215T and H8S/2215C. Reserved in H8S/2215.
9. The DREQ signal is not used for auto-request. The CPU can activate the DMAC using any flags
and interrupts.
