Note : SCKE bit = “0” when XCKE bit = “1 ”, or XCKE bit = “0”.
The b15 to b8 of this register are interrupt status bits. When the bit of the Interrupt Enable Register
corresponding to these bits are set to “1” (interrupt enable), the interrupt occurs by setting these bits to “1”.
This bit indicates the change of Vbus input.
This bit is set to “1” (Vbus interrupt occurs) when the Vbus input changes (“L”->“H” or “H”->“L”).
This bit is cleared to “0” by writing “0” (interrupt is cleared).
This bit is set to “1” and can be read out even if the clock is not supplied (Note). This bit can also be cleared by
writing “0”. In case the clock is not supplied, make sure to write “1” after writing “0” (no further interrupt will
be accepted).
