ISP1562
USB PCI Host Controller
The slave address that the ISP1562 uses to access the EEPROM is 1010000b. Page
mode addressing is not supported. Therefore, pins A0, A1 and A2 of the EEPROM must
be connected to ground (logic 0).
9.3 Information loading from EEPROM
Figure 6
shows the content of the EEPROM memory. If the EEPROM is not present, the
default values of Device ID, Vendor ID, subsystem VID and subsystem DID assigned to
Philips Semiconductors by PCI-SIG will be loaded. For default values, see
Table 3
.
10. Power management
10.1 PCI bus power states
The PCI bus can be characterized by one of the four power management states: B0, B1,
B2 and B3.
B0 state (PCI clock = 33 MHz, PCI bus power = on) —
This corresponds to the bus
being fully operational.
B1 state (PCI clock = intermittent clock operation mode, PCI bus power = on) —
When a PCI bus is in B1, PCI V
CC
is still applied to all devices on the bus. No bus
transactions, however, are allowed to take place on the bus. The B1 state indicates a
perpetual idle state on the PCI bus.
B2 state (PCI clock = stop, PCI bus power = on) —
PCI V
CC
is still applied on the bus,
but the clock is stopped and held in the LOW state.
B3 state (PCI clock = stop, PCI bus power = off) —
PCI V
CC
is removed from all
devices on the PCI bus segment.
L = LOW; H = HIGH.
