DIFFERENTIAL CLOCK TRISTATE
To minimize power consumption, CPU[2:0] clock outputs are individually configurable through SMBus to be driven or tristated during PD and CPU_STOP#
mode and the SRC clock is configurable to be driven or tristated during PCI_STOP# and PD mode. Each differential clock (SRC, CPU[2:0]) output can be
disabled by setting the corresponding output’s register OE bit to “0” (disable). Disabled outputs are to be tristated regardless of “CPU_STOP”, “SRC_STOP”
and “PD” register bit settings.

NOTES:
1. Each output has four corresponding control register bits; OE, PD, CPU_STOP, and “Free Running”.
2. IREF x 6 and IREF x 2 is the output current in the corresponding mode.
3. See CONTROL REGISTERS section for bit address.
