Notes:
1. Sampled, not 100% tested.
2. This specification is applied for not only the device power-up but also the normal operations. t_R (Max.) and t_F (Max.) for
#RESET are 100 µS/V
Glitch Noises
Do not input the glitch noises which are below V_IH (Min.) or above V_IL (Max.) on address, data, reset,
and control signals, as shown in Figure 19 (b). The acceptable glitch noises are illustrated in Figure 19
(a).
