DESCRIPTION
3.3V PCI clock output or Clock Request control A for either SRC0 or SRC2 pair
The power-up default is PCI0 output, but this pin may also be used as a Clock Request control
of SRC pair 0 or SRC pair 2 via SMBus. Before configuring this pin as a Clock Request Pin, the
PCI output must first be disabled in byte 2, bit 0 of SMBus address space . After the PCI output
is disabled (high-Z), the pin can then be set to serve as a Clock Request pin for either SRC pair
2 or pair 0 using the CR#_A_EN bit located in byte 5 of SMBUs address space.
Byte 5, bit 7
0 = PCI0 enabled (default)
1= CR#_A enabled. Byte 5, bit 6 controls whether CR#_A controls SRC0 or SRC2 pair
Byte 5, bit 6
0 = CR#_A controls SRC0 pair (default),
1= CR#_A controls SRC2 pair
Power supply pin for the PCI outputs, 3.3V nominal
3.3V PCI clock output/Clock Request control B for either SRC1 or SRC4 pair
The power-up default is PCI1 output, but this pin may also be used as a Clock Request control
of SRC pair 1 or SRC pair 4 via SMBus. Before configuring this pin as a Clock Request Pin, the
PCI output must first be disabled in byte 2, bit 1 of SMBus address space . After the PCI output
is disabled (high-Z), the pin can then be set to serve as a Clock Request pin for either SRC pair
1 or pair 4 using the CR#_B_EN bit located in byte 5 of SMBUs address space.
Byte 5, bit 5
0 = PCI1 enabled (default)
1= CR#_B enabled. Byte 5, bit 6 controls whether CR#_B controls SRC1 or SRC4 pair
Byte 5, bit 4
0 = CR#_B controls SRC1 pair (default)
1= CR#_B controls SRC4 pair
3.3V PCI clock output / Trusted Mode Enable (TME) Latched Input. This pin is sampled on
power-up as follows
0 = Overclocking of CPU and SRC Allowed
1 = Overclocking of CPU and SRC NOT allowed
After being sampled on power-up, this pin becomes a 3.3V PCI Output
3.3V PCI clock output.
3.3V PCI clock output / SRC5 pair or PCI_STOP#/CPU_STOP# enable strap. On powerup, the
logic value on this pin determines if the SRC5 pair is enabled or if CPU_STOP#/PCI_STOP# is
enabled (pins 37 and 38). The latched value controls the pin function on pins 37 and 38 as
follows
0 = PCI_STOP#/CPU_STOP#
1 = SRC5/SRC5#
Free running PCI clock output and ITP/SRC8 enable strap. This output is not affected by the
state of the PCI_STOP# pin. On powerup, the state of this pin determines whether pins 38 and
39 are an ITP or SRC pair.
0 =SRC8/SRC8#
1 = ITP/ITP#
Ground for PCI clocks.
Power supply for USB clock, nominal 3.3V.
Fixed 48MHz USB clock output. 3.3V./ 3.3V tolerant input for CPU frequency selection. Refer to
input electrical characteristics for Vil_FS and Vih_FS values.
Ground pin for the 48MHz outputs.
Power supply for DOT96 outputs, VDD96_IO is 1.05 to 3.3V with +/-5% tolerance
True clock of SRC or DOT96. The power-up default function is SRC0. After powerup, this pin
function may be changed to DOT96 via SMBus Byte 1, bit 7 as follows:
0= SRC0
1=DOT96
Complement clock of SRC or DOT96. The power-up default function is SRC0#. After powerup,
this pin function may be changed to DOT96# via SMBus Byte 1, bit 7 as follows
0= SRC0#
1=DOT96#
Ground pin for the DOT96 clocks.
Power supply for SRC / SE1 and SE2 clocks, 3.3V nominal.
