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