USB interrupt enable falling register
Address 10h-12h (Read), 10h (Write), 11h (Set), 12h (Clear)
If set, the bits in this register cause an interrupt event notification to be generated when the
corresponding PHY signal changes from high to low. By default, all transitions are enabled.
RxActive and RxError must always be communicated immediately and so are not included
in this register. Interrupt circuitry can be powered down in any mode when both rising and
falling edge enables are disabled. To ensure interrupts are detectable when clock is
powered down, the link should enable both rising and falling edges.
USB interrupt status register
Address 13h (Read-only)
These bits indicate the current value of the interrupt source signal. Interrupt circuitry can be
powered down in any mode when both rising and falling edge enables are disabled. To
ensure interrupts are detectable when clock is powered down, the link should enable both
rising and falling edges.

Current value of UTMI+ Host disconnect output. Applicable only in
host mode. Automatically reset to 0b when Low-Power Mode is
entered.
Current value of UTMI+VbusValid output.
Current value of UTMI+SessValid output. SessValid is the same as
UTMI+ AValid.
Current value of UTMI+SessEnd output.
Current value of UTMI+ID output. ID is valid 50ms after IdPullup is
set to 1b, otherwise ID is undefined and should be ignored.
