Local Bus

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.
