Applications Information
Interfacing to μPs with Bidirectional
Reset Pins
Microprocessors with bidirectional reset pins can inter-
face directly with the open-drain
RST
output options.
However, conditions might occur in which the push-pull
output versions experience logic contention with the
bidirectional reset pin of the μP. Connect a 10k
resis-
tor between
RST
and the μP
’
s reset I/O port to prevent
logic contention (Figure 5).
