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

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.

True clock of differential SRC clock pair/ Clock Request control C for either SRC0 or SRC2 pair
The power-up default is SRCCLK3 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 SRC3 output must first be
disabled in byte 4, bit 7 of SMBus address space . After the SRC3 output is disabled, the pin can then be set to
serve as a Clock Request pin for either SRC pair 2 or pair 0 using the CR#_C_EN bit located in byte 5 of SMBUs
address space.
Byte 5, bit 3
0 = SRC3 enabled (default)
1= CR#_C enabled. Byte 5, bit 2 controls whether CR#_C controls SRC0 or SRC2 pair
Byte 5, bit 2
0 = CR#_C controls SRC0 pair (default),
1= CR#_C controls SRC2 pair
Complementary clock of differential SRC clock pair/ Clock Request control D for either SRC1 or SRC4 pair
The power-up default is SRCCLK3 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 SRC3 output must first be
disabled in byte 4, bit 7 of SMBus address space . After the SRC3 output is disabled, the pin can then be set to
serve as a Clock Request pin for either SRC pair 1 or pair 4 using the CR#_D_EN bit located in byte 5 of SMBUs

If power-up w/ V>2.0V then use TEST_SEL
If power-up w/ V<2.0V then use FSLC
FSLB/TEST_MODE -->low Vth input
TEST_MODE is a real time input
If TEST_SEL HW pin is 0 during power-up,
test mode can be invoked through B9b3.
If test mode is invoked by B9b3, only B9b4
is used to select HI-Z or REF/N
FSLB/TEST_Mode pin is not used.
