Local bus clock to output high impedance for LAD/LDP
Notes:
1. The symbols used for timing specifications follow the pattern of t
2. All timings are in reference to falling edge of LCLK0 (for all outputs and for LGTA and LUPWAIT inputs) or rising edge of
3. All signals are measured from OV
4. Input timings are measured at the pin.
