LCLK cycle time
Input setup to LCLK (except LGTA/LUPWAIT)
Input hold from LCLK (except LGTA/LUPWAIT)
LGTA valid time
LUPWAIT valid time
LALE negedge to LAD (address phase) invalid (address latch hold time)
LALE valid time
Output setup from LCLK (except LAD[23:0] and LALE)
Output hold from LCLK (except LAD[23:0] and LALE)
LAD[23:0] output setup from LCLK
LAD[23:0] output hold from LCLK
LCLK to output high impedance for LAD[23:0]
Notes:
1. A negative hold time means that the signal could be invalid before the LCLK rising edge.
