Figure 68 and Figure 69 depict the timings pertaining to the PCMCIA module, each of which is an
example of one clock of strobe set-up time and one clock of strobe hold time. Table 53 lists the timing
parameters.
Table 52. Parallel Interface Timing Parameters1
1 Timing is guaranteed for NVCC from 2.7 through 3.1 V and up to a maximum overdrive NVCC of 3.3 V. See NVCC restrictions
