20.4 Reset Timing Specifications
Table 20-8 lists specifications for the reset timing parameters shown in Figure 20-14.
Figure 20-14 shows reset timing for the values in Table 20-8.
Note: Mode selects are registered on the rising CLKIN edge before the cycle in which RSTI is
recognized as being negated.
