However, if the master clock input can encounter a high clock or low clock period of less than 20 ns, then
RESET should be applied during this time. There are two recommended control procedures for this case,
depending upon whether the DBSPD terminal or the serial control interface is used. These control sequences
are shown in Figure 45 and Figure 46.
Because this sequence employs the RESET terminal the internal register settings are set to the default values.
