Notes: 1. This bit is initialized to B'0 by a power-on reset and B'1 by a USB bus reset.
2. These bits are initialized to B'000 by a power-on reset and B'001 by a USB bus reset.
3. This bit is initialized to 0 when the level of the VBUS pin input is high and 1 when low.
4. To clear the VBINT, RESM, SOFR, DVST, or CTRT bit, write 0 only to the bits to be
cleared; write 1 to the other bits. Do not write 0 to the status bits indicating 0.
5. This module can detect a change in the status indicated by the VBINT and RESM bits
even while the clock supply is stopped (while SCKE is 0), and outputs interrupts when
the corresponding interrupt enable bits are enabled. Clearing the status should be done
after enabling the clock supply.
6. A change in the status of the RESM, DVST, and CTRT bits occur only when the
function controller function is selected; disable the corresponding interrupt enable bits
(set to 0) when the host controller function is selected.
7. Only 0 can be written.
26.3.17 Interrupt Status Register 1 (INTSTS1)
INTSTS1 is a register that is used to confirm interrupt status.
The various interrupts indicated by the bits in this register should be enabled only when the host
controller function is selected.
This register is initialized by a power-on reset.
