Figure 23. Synchronous long hardware reset (EA = 1)
1. If during the reset condition (RSTIN low), RPD voltage drops below the threshold voltage (about 2.5 V for
2. Minimum RSTIN low pulse duration shall also be longer than 500 ns to guarantee the pulse is not masked
5V operation), the asynchronous reset is then immediately entered. Even if RPD returns above the
threshold,the reset is defnitively taken as asynchronous.
