DESCRIPTION
Ground for SRC clocks
SRC7 complement or Clock Request control E for SRC6 pair
The power-up default is SRC7#, but this pin may also be used as a Clock Request control of
SRC6 via SMBus. Before configuring this pin as a Clock Request Pin, the SRC7 output pair
must first be disabled in byte 3, bit 3 of SMBus configuration space . After the SRC output is
disabled (high-Z), the pin can then be set to serve as a Clock Request for SRC6 pair using byte
6, bit 7 of SMBus configuration space
Byte 6, bit 7
0 = SRC7# enabled (default)
1= CR#_E controls SRC6.
SRC7 true or Clock Request control 8 for SRC8 pair
The power-up default is SRC7, but this pin may also be used as a Clock Request control of
SRC8 via SMBus. Before configuring this pin as a Clock Request Pin, the SRC7 output pair
must first be disabled in byte 3, bit 3 of SMBus configuration space After the SRC output is
disabled (high-Z), the pin can then be set to serve as a Clock Request for SRC8 pair using byte
6, bit 6 of SMBus configuration space
Byte 6, bit 6
0 = SRC7# enabled (default)
1 = CR#_F controls SRC8.
1.05V to 3.3V from external power supply
Complement clock of low power differential CPU2/Complement clock of differential SRC pair.
The function of this pin is determined by the latched input value on pin 7, PCIF5/ITP_EN on
powerup. The function is as follows:
Pin 7 latched input Value
0 = SRC8#
1 = ITP#
True clock of low power differential CPU2/True clock of differential SRC pair. The function of this
pin is determined by the latched input value on pin 7, PCIF5/ITP_EN on powerup. The function is
as follows:
Pin 7 latched input Value
0 = SRC8
1 = ITP
No Connect
1.05V to 3.3V from external power supply
Complement clock of low power differenatial CPU clock pair. This clock will be free-running
during iAMT.
True clock of low power differential CPU clock pair. This clock will be free-running during iAMT.
Ground Pin for CPU Outputs
Complement clock of low power differential CPU clock pair.
True clock of low power differential CPU clock pair.
Power Supply 3.3V nominal.
Notifies CK505 to sample latched inputs, or iAMT entry/exit, or PWRDWN# mode
Vil_FS and Vih_FS values. TEST_MODE is a real time input to select between Hi-Z and REF/N
divider mode while in test mode. Refer to Test Clarification Table.
3.3V tolerant input for CPU frequency selection. Refer to input electrical characteristics for
