The bits of the USB Interrupt Latch register are automatically set by the ISP1504x1 when
an unmasked change occurs on the corresponding interrupt source signal. The
ISP1504x1 will automatically clear all bits when the link reads this register, or when the
PHY enters low-power or serial mode.
Remark: It is optional for the link to read this register when the clock is running because
all signal information will automatically be sent to the link through the RXCMD byte.
The bit allocation of this register is given in
