Figure 81.

Synchronous long hardware reset (EA = 1)

If RPD voltage drops below the threshold voltage (about 2.5 V for 5 V operation) during the reset condition (

RSTIN low),

an asynchronous reset is entered immediately. Even if RPD returns above teh threshold, the reset is taken as

asychronous.

The minimum RSTIN low pulse duration must be longer than 500 ns, to guarantee the pulse is not masked by the internal

filter (see Section 21.1: Idle mode on page 240).

At this time RSTF is sampled low

so it is definitely a long reset
