Table 39.
This register (see
Table 41.
The bits of the USB_INTR_L register are automatically set by the ISP1705 when an
unmasked change occurs on the corresponding interrupt source signal. The ISP1705 will
automatically clear all bits when the link reads this register, or when the PHY enters
low-power 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
