transition. All differential clocks will be held high on the next high to low transition of the complimentary clock. If the control register determining to drive mode
is set to ‘tri-state’, the differential pair will be stopped in tri-state mode, undriven. When the drive mode but corresponding to the CPU or SRC clock of interest
is set to ‘0’ the true clock will be driven high at 2 x I

PROGRAMMABLE FLEXPC™ CLOCK FOR P4 PROCESSOR
PD is an asynchronous active low input used to shut off all clocks cleanly prior to clock power. When PD is asserted low all clocks will be driven low before
PD should be sampled low by two consecutive CPU# rising edges before stopping clocks. All single-ended clocks will be held low on their next high to low
