TCM809/TCM810
2.3
Controllers and Processors With
Bidirectional I/O Pins
Some microcontrollers have bi-directional reset pins.
Depending on the current drive capability of the control-
ler pin, an indeterminate logic level may result if there
is a logic conflict. This can be avoided by adding a
4.7 k
resistor in series with the output of the TCM809/
TCM810 (Figure 2-3). 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
microcontroller, the buffer should be connected as
shown with the solid line.
