Description
Fast-PCI Clock Selects. These strap signals are used to
set the internal Fast-PCI clock.
00 = 33.3 MHz
01 = 48 MHz
10 = 66.7 MHz
11 = 33.3 MHz
During system reset, an internal pull-down resistor of 100
KΩ exists on these balls. An external pull-up or pull-down
resistor of 1.5 KΩ must be used.
Maximum Core Clock Multiplier. These strap signals
are used to set the maximum allowed multiplier value for
the core clock.
During system reset, an internal pull-down resistor of 100
KΩ exists on these balls. An external pull-up or pull-down
resistor of 1.5 KΩ must be used.
Boot ROM is 16 Bits Wide. This strap signal enables
the optional 16-bit wide Sub-ISA bus.
During system reset, an internal pull-down resistor of 100
KΩ exists on these balls. An external pull-up or pull-down
resistor of 1.5 KΩ must be used.
LPC_ROM. This strap signal forces selecting of the LPC
bus and sets bit F0BAR1+I/O Offset 10h[15], LPC ROM
Addressing Enable. It enables the SC2200 to boot from a
ROM connected to the LPC bus.
During system reset, an internal pull-down resistor of 100
KΩ exists on these balls. An external pull-up or pull-down
resistor of 1.5 KΩ must be used.
TFT Present. A strap used to select multiplexing of TFT
signals at power-up. Enables using TFT instead of Paral-
lel Port, ACB1, and GPIO17.
During system reset, an internal pull-down resistor of 100
KΩ exists on these balls. An external pull-up or pull-down
resistor of 1.5 KΩ must be used.
Fast-PCI Monitoring. The strap on this ball forces selec-
tion of Fast-PCI monitoring signals. For normal operation,
strap this signal low using a 1.5 KΩ resistor. The value of
this strap can be read on the MCR[30].
Device ID. Together, the straps on these signals define
the system-level chip ID.
The value of DID1 can be read in the MCR[29]. The
value of DID0 can be read in the MCR[31].
DID0 must have a pull-up resistor of 1.5 KΩ and DID1
must have a pull-down resistor of 1.5 KΩ.
Power On Reset. POR# is the system reset signal gen-
erated from the power supply to indicate that the system
should be reset.
