Output Signals:
MPC8640 and MPC8640D Integrated Host Processor Hardware Specifications, Rev. 3
Input Signals:
In PLL bypass mode, LCLK[n] is the inverted version of the internal clock
with the delay of
of the internal clock and are captured at falling edge of the internal clock,
with the exception of the LGTA/LUPWAIT signal, which is captured at the
rising edge of the internal clock.
