Local Bus
Figure 27 shows the local bus signals in PLL bypass mode.
Figure 27. Local Bus Signals (PLL Bypass Mode)
NOTE
In PLL bypass mode, LCLK[n] is the inverted version of the internal clock
with the delay of tLBKHKT. In this mode, signals are launched at the rising edge
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.
Output Signals:
LA[27:31]/LBCTL/LBCKE/LOE/
