7.8 Noise Filtering Timing for H/W Reset

Device must filter out 5ns or less pulse width for noise immunity

Figure 9: Noise Filtering Timing for H/W Reset

Device must not detect these rising edge.

Device must not detect 5ns or less of positive or negative RST_n pulse. Device must detect more than or equal

to 1us of positive or negative RST_n pulse width.
