Processors With Bidirectional I/O Pins
Some
Ps (such as Motorola 68HC11) have bi-direc-
tional reset pins. Depending on the current drive capability
of the processor pin, an indeterminate logic level may result
if there is a logic conflict. This can be avoided by adding a
4.7k
resistor in series with the output of the TCM809/810
(Figure 3). If there are other components in the system which
require a reset signal, they should be buffered so as not to
load the reset line. If the other components are required to
follow the reset I/O of the
P, the buffer should be connected
as shown with the solid line.
