7.6 GoodLink (in DC)
Indication of a good USB connection is provided at pin GL through GoodLink
technology. During enumeration the LED indicator will blink on momentarily. When
the ISP1161 has been successfully enumerated (the device address is set), the LED
indicator will remain permanently on. Upon each successful packet transfer (with
ACK) to and from the ISP1161 the LED will blink off for 100 ms. During ‘suspend’
state the LED will remain off.
This feature provides a user-friendly indicator of the status of the USB device, the
connected hub and the USB traffic. It is a useful field diagnostics tool for isolating
faulty equipment. It can therefore help to reduce field support and hotline overhead.
7.7 Suspend and wakeup (in DC)
ISP1161’s DC also can be put into suspended state by toggling bit 5, GOSUSP, of the
Mode Register. Pin D_SUSPEND is used for the DC’s suspended state sensing
output. The polarity of D_SUSPEND pin can be changed by setting bit 2, PWROFF,
of the Hardware Configuration Register.
There are some ways to resume ISP1161’s DC from the suspended state:
By USB host, drivers a K-state on the USB bus (global resume)
By pin D_WAKEUP or CS.
Figure 8
shows the timing relationship for DC going into suspended state, and
resuming from the suspended state.

Microprocessor bus interface
8.1 I/O addressing mode
ISP1161 provides I/O addressing mode for external microprocessors to access its
internal control registers and FIFO buffer RAM. I/O addressing mode has the
advantage of reducing the pin count for address lines and so occupying less
microprocessor resources. ISP1161 uses only two address lines: A1 and A0 to
access the internal control registers and FIFO buffer RAM. Therefore, ISP1161
occupies only four I/O ports or four memory locations of a microprocessor. External
