DESCRIPTION
49
GNDSRC
PWR Ground for SRC clocks
50
SRCC7/CR#_E
I/O
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.
51
SRCT7/CR#_F
I/O
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.
52
VDDSRC_IO
PWR Power supply for SRC outputs. VDDSRC_IO is 1.05 to 3.3V with +/-5% tolerance
53
CPUC2_ITP/SRCC8
OUT
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#
54
CPUT2_ITP/SRCT8
OUT
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
55
NC
N/A
No Connect
56
VDDCPU_IO
PWR Supply for CPU outputs. VDDCPU_IO is 1.05 to 3.3V with +/-5% tolerance
57
CPUC1_F
OUT
Complement clock of low power differenatial CPU clock pair. This clock will be free-running during
iAMT.
58
CPUT1_F
OUT
True clock of low power differential CPU clock pair. This clock will be free-running during iAMT.
59
GNDCPU
PWR Ground Pin for CPU Outputs
60
CPUC0
OUT
Complement clock of low power differential CPU clock pair.
61
CPUT0
OUT
True clock of low power differential CPU clock pair.
62
VDDCPU
PWR Power Supply 3.3V nominal.
63
CK_PWRGD/PD#
IN
Notifies CK505 to sample latched inputs, or iAMT entry/exit, or PWRDWN# mode
64
FSLB/TEST_MODE
IN
3.3V tolerant input for CPU frequency selection. Refer to input electrical characteristics for 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.
